Why Does My Pellet Stove Keep Shutting Off [Fix Now]
Here are the most common reasons why your pellet stove is going out frequently and what you can do about it.
1. Insufficient Fuel In The Hopper
The hopper is an essential part of a pellet stove. A pellet stove works only by feeding pellets to the hopper. The pellet is the fuel.
In case there is no fuel in the hopper, the pellet stove will automatically shut off. Here are the solutions to this situation:
i) Feeding Pellets
Keep feeding pellets in the hopper. This will keep the hopper active and the pellet stove running.
ii) Clean The Hopper
Dirt and debris can clog the hopper. This may in turn prevent the pellet stove from functioning properly. So keep the hopper clean and free from any kind of obstructions.
2. The Fire Has Died
This is the most common reason behind the pellet stove shutting off. If you don’t feed pellets in your pellet stove every 20-30 minutes, the stove will shut off. The status light will let you know if this happens. What you should do is:
i) Properly Feeding Pellets
Maintaining the pellet feeding duration is not enough. You have to make sure that the pellet you are using is perfectly dry and perfectly sized. Only quality pellets will keep the pellet stove fire alive.
3. Faulty Stove Wiring
Faulty stove wiring can be one of the most common reasons why your pellet stove keeps shutting off at night. Every pellet stove has an outlet. These outlets provide energy to run the thermostat and fans.
If the wiring of these outlets or the wiring of the internal circuit board is damaged, your pellet stove may not function properly. If this is the case, then here is what you can do:
i) Check The Switches and Circuit Breaker
If the outlet voltage doesn’t reach its limit, it can cause your pellet stove not to work at all. Measure the power and make sure that nothing is preventing proper power supply.
ii) Proper Voltage Reading
Take a multimeter and set it to AC voltage. Use it to read the power from the terminal strip. The voltage should be 120V.
iii) Check All The Wiring
There are specific points where wires are very likely to lose connection. Check the following points in your pellet stove for faulty wiring-
- All the wiring points in the combustion & convection blower
- Wiring at the end of the igniter and auger motor
- Most importantly check the wiring at high and low limit thermodisc
If you find any frayed or cracked wires in these points, fix them as soon as possible. Change the wires if necessary. Replacing the wires can be the most effective solution in this case.
4. Pellet Stove Draft Is Too Low
The draft’s position determines the condition of the flame in the pellet stove. A low draft leads to a weak flame in the pellet stove.
However, if the draft is too low, then there may not be any flame at all. If that’s the case then here’s the solution to that:
i) Adjust The Draft
You will find a handle preferably on the right side of the stove. If you pull that stove, the draft will open up, and the flame will increase.
Don’t set the draft too high though. It will turn off the pellet stove.
5. The Damper Issue
A combustion air damper is a pipe that goes to the flame of the stove. Its function is to increase or decrease oxygen circulation.
So, it plays the role of adjusting the air to the fuel ratio so that the pellets burn at a desirable rate. If the damper loses its adjustment, the stove will shut off. So, here is what you can do:
i) Adjusting The Damper
The feed ratio determines what amount of pellets would lead from the hopper to fuel the flame.
If the ratio is high, there would be too much ash, whereas a very low ratio would lead the flame to go out. Here it’s recommended to set the ratio above low to have an ideal flame effect.
ii) Fix The Dampers
Check if the damper’s hinges are damaged or not. There can be holes in the damper as well. It might not close properly. Make sure to deal with all these issues.
6. Problem With Burn Pot
Burn pot helps your pellets to burn and radiate heat properly. If the burn pot is not precisely mounted, it can cause obstruction. This issue can prevent the pellets from burning. Here’s how to fix the issue:
i) Clean The Burn Pot
Throughout the burn process, a huge amount of broken pellets and small fuel particles remain in the burn pot.
Plus, clinkers and ashes fall through some of the ports of drawing air. All these create a jam and thus hamper the airflow.
Cleaning all these obstruction particles will fix the flame falling issue if it happens from this part. Here you can use an air compressor to clean the burn pot. Also, you can clean the pot by shaking it.
ii) Position The Burn Pot Correctly
Now check if the pot position is okay or not. If you have a perfect-sized burn pot, it should perfectly fit over the combustion air tube.
It needs to be placed about ⅛” away from the wall of the firebox. Make sure it’s positioned this way.
7. Problem With Combustion Tube
The system works with a tube which is known as a combustion air tube. The tube receives fresh air to operate in perfect combustion.
This process of combustion can be hampered if there are obstructions inside the tube. It may malfunction if there are any problems with the wires. Here’s how to fix the issue:
i) Remove The Obstructions
To clean any jam inside the tube, first, remove the damper and see if there are any obstructions inside the tube, even in the damper.
There can be elements restricting the airflow of the combustion air tube. If found, clean the jam particles.
ii) Check The Wiring
Make sure that all the wirings are properly connected. Faulty wiring can shut off the fan of the combustion air tube.
Plus, find out if there is any cut-up or damage in the whole wiring. If any damage is found, repair the wiring.
8. Feed Motor Or Combustion Blower Failure
Fire needs air to burn fluently. The combustion blower or the feed motor sucks air into the burn pot to allow combustion.
Pellets won’t burn properly if the feed motor fails to supply air. You can solve this issue in the following method:
i) Clean The Feed Motor
The feed motor may fail to supply air if it is clogged or covered by too much dust. As a result, the stove will shut off.
Here, you should clean the feed motor perfectly. To clean the dirt from the feed motor, you can use a blower to make the cleaning process simple and easy.
ii) Fixing The Motor Wiring
Faulty wiring can result in combustion blower failure. Check if the wiring is okay. Sometimes it may not be possible to fix the wiring. Replace the blower in that case.
9. Check The Air Flow
The Pellet stove requires an outside air supply in the stove. A pellet stove draws in air through the grills on the sides of the fireplace cover.
The stove may not work if the airflow is restricted. Here’s how you can deal with it:
i) Clean The Blockages In The Stove
Even tiny insignificant elements can block the airflow. It can be the unwanted obstruction in your pellet stove preventing the airflow.
Cleaning them thoroughly will make your pellet stove function better.
ii) Reposition Your Stove
If your pellet stove is located inside of the fireplace, then it can be a reason why the pellet stove keeps shutting off.
Reposition it. Move it ½” out of the fireplace. This will improve the airflow and prevent your stove from shutting down.
Basically, these were the main reasons why your pellet stove keeps shutting off. Our solutions will definitely help you deal with it.
How To Avoid Pellet Stove Shutting Off
It’s never a good sign if your pellet stove lights then go out. Such conditions can damage your pellet stove permanently. In that case, you will have to replace your pallet stove. That will be an expensive solution.
The best option for you is to prepare your pellet stove to avoid it shutting off abruptly. There are two ways for you to do that. The first option is to set up your pellet stove in the proper way.
And the second thing to do is, avoid setting up the pellet stove in the wrong place.
Setting Up Pellet Stove In The Right Way
It’s not hard to set up a pellet stove perfectly so that it doesn’t shut off. But it is possible only with accurate instructions.
You will find that here. But before getting into the setup process, gather the following tools first:
- Utility knife
- Drill and drill bit
- Stud finder
After you have collected all these tools, you can get started. Even if you have already installed your pellet stove, it’s not too late.
You can reinstall it very easily. Here’s how to properly set up a pellet stove in 5 easy steps:
1. Setting Up The Position
Take a non-combustive heat pad and position it where you want your pellet stove to be. While choosing the perfect position, there are specific points you should avoid.
We have discussed those points in this article. However, make sure that the pad extends 6 inches in front and on each side of the stove.
A different pellet stove requires a different drilling process. The best thing to do in this case is to consult the user manual.
Follow the instructions in the user manual and do cutting or drilling according to the prescribed measurement.
3. Making Way For The Vent
Firstly, use a stud finder to ensure that the vent path is clear. Any form of obstruction can cause your pellet stove to shut off. Use the utility knife to cut the wall and use a jigsaw to do further cutting.
4. Setting Up The Vent
Now install the vent thimble first. It helps to install the venting pipe properly. Slide the vent into the slot you cut previously, and that would be all.
5. Installing The Pellet Stove Pipe
Take help from your pellet stove instruction manual to make sure you are installing the recommended pipe. Install the thimble according to the user manual.
If you put up your pellet stove following these steps, you will not have the problem of the pellet stove shutting off anymore.
But this is not all. There are certainly more things you must keep in mind to keep your pellet stove burning.
What To Avoid While Installing A Pellet Stove
Even if you follow the points discussed above, you may make mistakes while setting up a pellet stove. These futile mistakes can cause your pellet stove to shut off every now and then.
You must not install a pellet stove in the following positions:
- In the bedroom
- Near a window
- Directly in front of a door
- In the middle of the room

My stove has power but motor auger will not work any suggestions
Clean the auger motor. Also, check the auger wiring and fix it.
I have my pellet stove professionally cleaned once a year. Actually, the stove tells me when to professionally clean it; but, I clean the fire pot, and ash collector, and fire wall every Sunday. During the week I turn the stove off at least once a day to clean the fire pot and push the soot into the ash collector. My stove is relatively small and buildup is readily seen. We were using clean fire fir pellets. These pellets were fantastic and caused very little soot. The clean fire fir pellets were not available early this year and we had to settle for a cheaper combination of pellets. The cheaper pellets create a tremendous amount of ash and I truly need to clean the fire pot and ash from the surrounding area once a day or my flame is very low thus low heat production. I do have a real question. When the professional cleaned the stove last spring, he did not allow enough pellets to fill the fire pot and it takes me 4-5 tries to light the fire in the fire pot. I know you are not supposed to add fuel to the fire pot but that is the only way my fire would start. I add a handfull of pellets to the cleaned fire pot and my fire starts immediately. QUESTION: So, how do I increase the amount of pellets automatically falling into the fire pot so I do not need to add pellets myself?
Do you have an automatic adjustment system? If yes, adjust the feed rate. If not, then contact that professional who cleaned the stove last spring and decrease the pellet dropping rate.
My pellet stove runs 5 minutes and shuts down with a Eso1 code. Cleveland iron works P130 model. Need help to fix issue
ESO1 = Temperature sensor 1 is open-circuited. Contact customer support to fix it.
Press power button green light comes on and then goes to off and stove will not go into start up mode. Have checked all vacuum switches and safety switches
The issue is a sign that your stove needs cleaning thoroughly including the combustion chamber and hopper as maybe the fuel is not getting the fire because of being blocked. Plus, clean all vents and check all gaskets, and repair or replace them if needed. Adjust the airflow setting. Also, check whether any part is worn or not that may need to repair or replace.
First, follow the instructions to solve the issue. If it doesn’t work, take help from a technician.
Lopi Deerfield starts up, I can hear and see pellets being pushing into pan, they ignite and flame looks great. Both left and right blowers turn on after 15 minutes or so…then pellets stop being fed into the pan (but auger keeps spinning, just not pushing anything out)…and flames dies slowly. I then get a “Service loss of flame (pof)” code displayed…I’ve cleaned everything…please help!
Generally, this type of issue happens due to one or more reasons like an empty hopper, a jammed auger, a failed motor, obstruction in the hopper, and lack of combustion air in the system.
Also, due to poor airflow, the safety switches get tripped and prevent the auger from feeding pellets.
Well, to fix the issue follow our solution guide in pellet stove auger stops feeding pellets.
Hopefully, your problem will be solved.
Wish you all the best!
I have a older stove that used to work great. Now it will come on run for few minutes then shut down. I have changed thermocuplar also had box checked and they work great. The stove is not that clean however I cannot clean such things as fire bowl. Wiring I do not know how to check also I do not have money for someone to come out and do for me.
Your pellet stove shuts off after a few minutes due to one or more reasons like insufficient fuel, dried-up fire, faulty wiring, low drafting, damper issue, air flow issue, the problem with the burn pot, and the problem with the combustion.
