Why is my comfort zone infrared heater not working?
Your infrared heater is not working because you may not plug it in. Alternatively, the air filter gets clogged, or insufficient air may flow to the heater.
Can I leave the infrared heater on all the time?
Yes, you can leave your infrared heater overnight as it is entirely safe. However, we recommend you turn off the unit when you are asleep or go outside.
Do infrared heaters wear out?
There is no moving part in the infrared heater. So, there is no risk of wear out.
Do infrared heaters use a lot of electricity?
Yes, some infrared heaters use a lot of electricity to operate. However, you can find the label on which the manufacturer writes how much electricity it takes to run. Generally, most heaters require 1500 wattages of electricity to operate smoothly.
How long do infrared heaters last?
Infrared heaters will last around 20,000 hours.
How much does it cost to run a 1500-watt heater for 24 hours?
Generally, it depends on how many bucks you give to your local electric company per KW. For example, if you pay $0.20 per KW, apply the below formula to know the cost. The wattage of the Heater x Hours ÷ 1000 x Price. Now, let’s calculate: 1500 x 24 ÷ 1000 x $0.20= 7.2. Indeed, a 1500-watt heater will spend you $7.2 per day if you run it for 24 hours.
You learned why the heater is malfunctioning and its solution from this Comfort Zone Infrared Heater Troubleshooting guide.

I bought a CZ220 5,000 watt from Amazon. Hooked it up, verified 240 to the lugs, 30 amp breaker at the box. Power light comes on, turn the knob and nothing. Use switch settings I, II, III and cycle the knob, nothing. I hear a click each time knob moves from the OFF position but nothing beyond that.
I can see power at the switch but nothing when the switch is moved from OFF position.
Anyone have an idea?
As it’s a new one, you should first contact customer care for getting a solution according to the warranty procedure.

My Comfort Zone Quartz Tower Heater has started to make a burning smell when it’s in use. I’ve had it for about 4/5 months and have been using it pretty steadily to heat my bedroom. The smell is new.. never did it before. I have stopped using it for fear that it’s become a fire hazard.
Any thoughts? Thank you.
It could be due to an electrical problem or if the space heater is faulty itself. Make sure that the space heater itself is not melting or any plastic is melting inside it. Also, ensure you are not using an extension cord. Plus, such a smell is usually the result of accumulated dust on burners, air ducts, or other furnace parts. So, first, clean the heater and find if the smell is still. If you still smell, it would be wise to contact a technician.
I have an old, small Comfort Zone personal heater, maybe 12 years or so old; I don’t know if its an infrared heater. It has 2 knobs, one for temp control and the other with off, fan, low and high. It was working great until I moved it to another location in my condo and then this morning moved it back to where I usually have it. Turns on great but no heat. I took off the back and dropped it while unscrewing it. Didn’t see anything unconnected. Put it back together and it turns on but no fan. The heater coil turns red, I don’t remember that being red before I took it apart but I wasn’t paying attention. Do you think dropping the heater broke the fan? One of the screws is missing. Would not having one of the screws cause the fan to not work? I’m not mechanically minded….
The answer is given in your other comment.
Roseanne here again. I took it apart again, put it back together and now the fan works but no red coil and no heat. Maybe it’s time to replace. This has been a great fan tho. Model CZ40 if that helps.
First, make sure the unit is plugged in that is free of damage. Plus, check the circuit breaker and electrical socket and ensure they are working properly. Also, check the air filters and clean them if you get them clogged. Clogged filters or insufficient airflow to the heater could be the reason for your heater not working.
If it doesn’t work, take help from a technician.
My Comfort Furnace Infrared Heater 1500 will run well for a while, then we’ll go in the room and the temperature is 84 degrees when the setting is on 72 degrees. Can anyone explain how this can occur?
It is an overheating issue. This type of problem generally happens due to a dusty air filter that blocks the airflow. Consequently, heat accumulates inside the unit and ultimately shuts down the unit.
To solve the issue do the followings-
1. First off, unplug your unit or electric heater from the outlet. Then, plug the electric cord into the outlet a few seconds later.
2. Clean the air filter often, which you can find on the back of your heater.
3. Bring your heater at least 3 feet away from the wall.
Hopefully, your issue will be solved.
I installed a 7500 watt electric comfort zone heater. The digital thermostat is set at 60degrees and shows a temperature of 61degrees. I put a thermometer in the garage and it shows 42 degrees. No matter where I set the temperature it maintains a 20 degree difference between the inside of the garage and the digital display on the heater. What can I do?
Check the filter which could be the culprit behind the issue. In fact, a clogged filter restricts the airflow & consequently, your heater can’t push the warm air out.
Well, to fix the issue, replace the filter.
Hopefully, your problem will be solved.
Wish you all the best!
MyCZ1500Comfort Zone heater displays AO5 when turned on and continues to cycle the AO5 code about every 3 seconds without ever turning on. Any advice?

Best of luck!
