Hi , I have a comfort zone heater. It was not working since yesterday. Front side power bulb is not glowing. Need help. Backside power red switch is glowing.

It is possible that there is a fuse inside the Comfort Zone Fireplace Heater model # CZFP20M that has blown, causing the artificial flame to stop working. You should check the owner's manual or contact the manufacturer to determine if there is a fuse in the unit and where it is located. It's also possible that the artificial flame stopped working due to a malfunction in the control module or other electrical component. In this case, it's recommended to get the unit inspected by a professional technician.

It's not uncommon for artificial flames to stop working, it could be due to a variety of issues such as a malfunction in the control module, a blown fuse, or a problem with the artificial flame itself. I recommend checking the owner's manual or contacting the manufacturer for troubleshooting steps or to see if there have been any known issues with the model you have. If you are unable to find a resolution or the problem persist, it's always best to get the unit inspected by a professional technician.

To locate replacement quartz bulbs for your Comfort Zone heater, you can try the following steps:

1. Check the manual: Your Comfort Zone heater should have come with a manual that includes information on replacement parts, including the type of bulbs needed. Check the manual to see if it specifies the type of quartz bulbs that are compatible with your heater.
2. Check the label: Look for a label or sticker on the heater that lists the make and model number. This information can help you find the correct replacement bulbs.
3. Contact the manufacturer: Comfort Zone is the manufacturer of the heater, so you can try contacting their customer service department to ask for assistance in finding replacement bulbs. They may be able to provide you with the specific bulbs you need, or they may direct you to an authorized dealer or retailer.
4. Search online: You can also search online for replacement quartz bulbs that are compatible with your Comfort Zone heater. Try searching for the make and model number of your heater, along with the keywords "quartz bulbs" or "replacement bulbs."

It's important to note that if the halogen lamp is also not coming on, there may be an issue with the heater's electrical system. In this case, it may be best to contact a professional electrician or appliance repair technician to diagnose and fix the issue.

if unit runs ok for 3 to five minutes then completely shuts all power lamps off , then its hi temp limit sensor (safety) has been tripped , this usually goes out due to failure of main temp control , in point of fact contacts in temp switch literally weld them self's together and cant separate to allow heater to control temp

Sounds like a bad control board... maybe swollen/leaky electrolytic capacitors.

Most of the new heaters dont glow red. Its a safety thing so it dont catch your sheets or curtains,couch,chair etc on fire. Because of the idiots in this world we cant get a good heater anymore. Thats just the way it is.

nothing works

The AO4 is a board used by Earthwise on the Comfort Zone Heater. The reading is the board being used. If the heater just gives that reading it may need to be reset. This can be done by pressing up, down and enter at the same time. If this does not work unplug and try it again. Hope this helps

dust and dirty air can be one problem or some object has fallen in to it you may need to get it cleaned

The bulbs on the older (pre-fall of 2010) Comfort zone heaters are in pairs... if one bulb of the pair is burnt out the other will not work. Also they are not easy to line up when replacing them back into the recepticle...they must line up perfectly to work.

On the comfort zone CZ7007, the #1 rocker switch is for 600 watts, the #2 rocker switch is for 900 watts. If you flip 1 and 2 both to on you will get 1500 watts. Which is 600 and 900 added together. There is no down position, but only on and off.
