Heatilator GC300 - Natural Gas

[sunguy]

Hello,
We bought a house this summer and have a Heatilator GC300 with fan installed in the family room. the house is 25 years old but I am unsure how old the fireplace is..Anyways, the fireplace runs for a few minutes then turns it off then restarts, then turns off..all by itself..The pilot line stays on...What can the issue be?
Thanks in advance.

How are you turning it on? Wall switch?

Yes, wall switch..The fan is also controlled by a wall switch. thx

Pull the switch & disconnect the wires. Touch them together & let the fireplace burn. If the symptoms don't return, replace the switch. If it still happens, let us know. We will figure it out.

I have a the same problem, replace the thermopile and for a few days the unit was fine. Pilot never goes out just he burner. So, I'd like too know if the wall switch was the cause for you burner to go out.
