10 Harman Pellet Stove Troubleshooting with Causes

May it be the problem with your P68 Harman pellet stove, or Harman XXV pellet stove, or Harman accentra 52i, it doesn’t matter. Our troubleshooting guide will work with every model of Harman stove. Today, we will be talking about the 10 prominent issues that you are very likely to face with your Harman pellet stove. So, let’s get started and fix the issues immediately.

Problem 1: Harman Pellet Stove Not Feeding At All

Sometimes the stove auger fails to feed the pellets when the lids or doors aren’t closed tightly. A blocked or clogged auger can cause the stove to stop feeding as well.

Solution: 

If the feed system does not work, your stove will not even start. In this case, you can follow these steps:

Step 1: Check The Hopper Tank

The first thing you must do is to check the hopper tank. Check the fuel tank and fill it in if it’s empty. The problem can be a clogged hopper as well. In that case, clear all the obstructions. 

Step 2: Ensure the Efficiency of Feed Motor 

You should check the fuel pot to make sure that there is enough starting gel and fuel in the fuel pot. Do this before lighting the stove. This will provide a sufficient amount of temperature to the ESP control and this will in turn help to activate the feed motor.

Step 3: Activating the Feeder Circuit

Make sure that the firebox draft is properly adjusted. Check if the gaskets are in perfect condition. The hopper lid and stove doors must be closed as well.  After meeting these criteria, the sensing switch in the feeder circuit will function properly and feed the fuel as required.

Step 4: Hopper Lid Needs to be Perfectly Placed

You have to ensure that the hopper lid is in direct contact with the lid position switch. If the hopper lid is not perfectly placed then it won’t function properly and as a result, your stove won’t feed pellets.

Step 5: Ensure Smooth Combustion

Never use damp pellets. Only the dry and properly processed pellets burn efficiently. Check the combustion blower and motor as well. This way you will be able to make sure your pellets will now burn without any further difficulty.

Basically, these are the 5 simple steps that you can follow if your stove does not feed the pellet.

Multi-repair Solution:

Changing or getting a new motor will reset your stove automatically. So, you will discover that the stove is working like a brand new one.

Problem 2: The Stove is Feeding Too Fast

If you are putting too much fuel in the burn chamber, this might cause the pellets to overfeed. The rate of feeding also depends on the adjuster. 

Solution:

If your pellets are feeding too fast, reduce the fuel or flame rate. Always clean the burn chamber before lighting. Dirt can cause damage. Hopefully, you will find the issue is fixed. Yet, if you find your stove keeps feeding, you can read our ultimate solution guide to Harman pellet stove keeps feeding pellets.

This is one of the major problems that you might face while using the Harman pellet stove. The stove might shut off if the sensors are not getting enough heat. Dirt or damaged areas can also be a reason behind the shutting off. 

Solution

Close the stove doors and lids very tightly. Use the right amount of pallets and make sure the air inside is balanced. This will reduce the chances of shutting down your stove.

Multi-Repair Solution:

The above process will help the stove to feed the pellets correctly. Also, it will help to reduce the weak flame. 

Problem 4: The Stove Burns Pellets Partially 

Insufficient air flow doesn’t support enough fire. A dirty burn pot prevents pellets from the burner. A dirty blower fan doesn’t allow enough air to flow inside of the burner. This, in turn, leaves the pellets partially burnt

Solution: 

Here are a few things you can do in case the pellets are only partially burned in the stove.

1. Set the fuel feed rate to low.

2. Ensure proper air to fuel mixture by observing the burn pot clean-out cover and air intake rate.

5. Examine the blower fan for debris and clean them if needed.

6. Take a look at the air chamber located under the burn pot to make sure there is no dirt.

You can ensure a proper flow of air and fuel, then you shouldn’t have the problem of partially burned pellets. 

Multi-Repair Solution:

Use a fresh batch of pellets to solve this issue. This way your pellet will properly burn on the stove.

Problem 5: The Stove Fire Goes Out: 

An inconsistent supply of fuel can cause the fire to go out. If the fuel hopper lid is not properly close then this can cause the fire to go out.

Solutions: 

Here are 3 things you can do to deal with this issue.

2. Make sure that the fuel hopper lid is closed properly.

Fixing these issues will assure a consistent fire.

Multi-repair Solution:

Change the fuel hopper and use a new batch of fuel. This way you will have a consistent flame for sure. And you won’t even have to do any cleaning.

3 Methods To Reset A Harman Pellet Stove

If your Harman pellet stove keeps shutting off or doesn’t work properly even after trying the troubleshooting discussed above then you probably need to reset your pellet stove.

Resetting a Harman pellet stove can solve the issues you can’t identify. But, do you know how you can reset a Harman pellet stove? Well, you will know in a minute if you keep reading on. Here’s how to reset a Harman pellet stove:

1. Use The Reset Button:

While many pellet stoves have a reset button, most of the pellet stoves don’t have any such system. If there is a reset button then you can sit back and relax while the stove goes through the process of resetting all by itself.

But, if your stove doesn’t have this system then you have to reset the pellet stove manually. In this case, you can simply reset the stove by allowing the pellets to burn out. There are two benefits of doing this:

(a) You won’t have to worry about moving the pellets

(b) You won’t have to wait for the stove to cool down

After the pellets are burned all the way, there won’t be any heat. This is how you will have a perfectly reset pellet stove without much hassle.

2. Try Turning Your Stove On and Off:

Another easy and effective way of resetting your pellet stove is turning it off and then on again. Your pellet stove must have a turn-on/off button. Take help from your stove’s manual if you can’t find the settings.

Once you have identified the buttons and turned the stove off, wait for 5 to 10 seconds before turning it on again. As most Harman pellet stoves don’t have a reset button, you can adapt this method for an efficient result.

3. Cleaning the Stove:

Sometimes the debris stuck in the stove can be the reason why it’s not working properly. In this case, cleaning your stove is enough. Try to thoroughly clean all the vents and the opening of the stove. 

You can open up the outer part of the stove to clean the inside as well. But consider detaching the parts of the stove only if you think you can place it properly again when you are done.  

What To Be Cautious About While Using Harman Pellet Stove

Just knowing how to reset your pellet stove and applying the instructions isn’t enough. There are some points you should be cautious about. If you are not attentive to these concerns, you may have to experience terrible accidents. Here are some major points you should be cautious about:

3. Always wait for the stove to cool down before proceeding to clean it.

4. Remember to follow the manual. Do not try to do anything on your own.

If you can keep these points and safety measures in your mind then you will be able to reset your Harman pellet stove without much difficulty.

However, if nothing works then you can call a mechanic. It’s better not to always take the risk.
