Gas Fireplace turns off after heating up | Hearth.com Questions and Answers

Gas Fireplace turns off after heating up - # 2176

Question:

Re: gas fireplace I just recently moved into new home that has a gas fireplace.  After running the fireplace for a few minutes the fireplaced turned off on it’s own.  I was hoping you might be able to give me some suggestions on what the problem might be.  This fireplace has an electronic igniter.  How often do you recommend I have the unit serviced and what should I be looking for when servicing?

Answer:

Could be quite a few things. Fireplaces with electric ignitors have a control sequence that goes something like this:

1. turn gas on
2. Spark to light gas
3. Check for heat from gas
4. Turn off the ignitor
5. ongoing - check for heat at flue of fireplace - turn unit off if too little of too much heat.

Based on that, it could be #3 or #5….

My guess is that it is a relatively simple repair (sensor or wire) IF you get the right service person.

Once it is working well, it should go for years with little or no service.
