What’s The Function Of Reset Button On A Heater

The reset button on a heater is used to turn it off quickly before it trips your circuit breaker. This button essentially resets your heater system.

Just like you need to restart your PC or your phone, your heater also needs to be restarted in different cases.

Modern-day furnaces come with a reset button. But even when there isn’t a reset button, heaters can still be reset. You just have to go over the process manually. A manual reset will have the same effect as resetting with the button.

How To Reset Comfort Zone Heater

Depending on your model, the procedure for resetting a comfort zone heater may differ slightly.

Most contemporary units, on the other hand, follow the same procedure: simply press and hold the two right buttons for at least three seconds. If that doesn’t reset the heater, you can manually reset the heater by doing the following.

Step 1: Remove the impediment and turn off the space heater.

Step 2: Turn the thermostat off.

Step 3: If you have an electric heater, disconnect it from the power source.

Step 4: Allow the machine to cool down for 10 to 15 minutes.

Step 5: Turn it back on. Check in for 10 minutes to see if it is evenly releasing heat.

When Do You need To Reset Your Comfort Zone Heater?

You need to reset your Comfort Zone heater while fixing the following Comfort Zone heater problems.

1. Heater Overheating

An error message for overheating will show up on your heater’s display if this ever happens.

When your heater is overheated, the unit will most likely get damaged if not shut off immediately. In this situation, to protect your heater press the reset button.

2. Heater Won’t Turn On

When your Comfort Zone heater won’t turn on though it’s getting power, you should first try to reset the heater to fix the issue.

In case pressing the reset button doesn’t help, you’ll need to further analyze the situation. Most likely, you have a bad heater component.

3. Error Messages

When different error messages appear in your heater’s display, the first and easiest solution to try is resetting the heater.

This will not fix your issue only when there is something deeper wrong with your heater that needs to be addressed. Otherwise, most error codes will go away once the heater is reset, especially, when your heater is new.

When Does Your Comfort Zone Heater Reset Automatically?

You’ll notice your heater reset button tripping on its own in some cases. This is normal as your heater is programmed to do this in specific cases. The following situations can cause your heater’s reset button to trip.

1. Bad High Limit Switch

If your heater’s high-limit switch is bad, this may cause your heater to restart automatically

2. Loose Wiring

Loose wiring in your heating element can also cause the reset button to trip.

3. Short Circuit In Heating Element

When your heating element has a short circuit it will cause excessive heat which can trip the reset button. You may need to replace the heating element to fix this.

4. Shortage Of Fuel

If you are out of fuel and have a gas or oil heater, the reset button may trip. Making sure there is fuel in the gas or oil tank is all it takes to cure this problem.

If this is the case, please be sure to inform the customer service representative that the tank is empty and that the tank will need to be primed when you contact for a refill. 

5. Blocked or Closed Gas Valves

Another reason the reset button continues tripping could be blocked or closed valves. Checking to see if any of the valves have been mistakenly closed could assist in resolving the issue.

6. Dirty Flame Sensor

The flame sensor rod can become clogged with dirt and debris over time, forcing the heater to reset. Keeping the flame sensor rod clean by wiping it off on a regular basis will help prevent this.

7. Dirty Air Filter

The heater’s reset button may trip due to a filthy or blocked air filter. Regularly changing or cleaning your HVAC air filter (at least once a quarter) will help to keep your heater in good working order and decrease the load on it.

8. Overheating

If a furnace doesn’t get enough air, it can overheat, causing the reset button to trip. Make sure the air filters are cleaned or replaced, and that the air vents are open enough for proper ventilation.

However, you can avoid the above troubles with the regular maintenance of your heater and keeping your heater in condition always.

Here, you can watch the tutorial on how to reset a space heater.


Why did my comfort zone heater turn off?

Your Comfort Zone heater keeps shutting off because it is too large for the room it’s being kept in. Oversized heaters can quickly heat up a place even before the heating cycle is complete. Plus, a dirty air filter, defective heating element, and faulty thermostat are responsible to shut off your heater.

How long can you run a comfort zone heater?

It is possible to leave space heaters on for an extended amount of time. You may easily leave a higher-end heater on for 10 hours or longer if you have one.

Why is my space heater blowing cold air?

The most likely reason for this is that you have a clogged-off air filter. You need to turn off your heater and ensure a clean filter.

Do infrared heaters use a lot of electricity?

Compared to a regular heater, an infrared heater is 30 to 40% more energy efficient. Infrared heaters use 7 watts per square foot (0.1 m2), whereas normal heaters use 10 watts.

Because infrared heaters heat objects before the air, they may work better in uninsulated spaces. In enclosed situations, Blue Flame heaters are usually superior. Infrared and blue flame heaters both have a 99.9% efficiency rating.
