Comfort zone infrared heater runs for a few minutes a then completely shuts off

order one online --check with manufacturer for distributor near you --or a heating store near you

There have been problems I have heard about these heaters take it back it should be under warranty .

If its to close to the wall it can shut off due to high temp

lack of actual heat transfer

i have a digital quartz infrared heater comfort zone cz20110. does the fan keep running all the time and when it reaches the temp to your room why doesn't it it shut off.

I had same problem with mine and found out that the timer was turned on make sure your timer time is set to 00 hope this helps

What is wrong with my Comfort Furnace heater if i have it turned off and it still keeps blowing ,Yet if i plug it back in it still comes on and i can turn it way down with it down on 55 and it will not shut of like it use to?

Take a look for new thermostat on amazon, here: Save Time Money and Energy with Induction Cooking. Wish you best of luck.

FYI...I have a customer that brought his Comfort Zone CZ2011C to me for service. It does exactly the same thing, just powers off after a few minutes of operation. I contacted the company and receive no help at all telling me that repair parts are unavailable. Really??? Absolutely the worst company I have ever dealt with in over 29 yrs of appliance repair....

Hi. I have the Comfort zone 1500 (cz 1500) and just ran into this AO5 problem. Turns out the thermostat was set lower than the actual room temperature. I just turned up the heater temp and it kicked right on. Hope this helps!
