Hello, I can help you with this. For clarification the unit lights and relights many time before reaching the set temp for the first time?
Thanks, XXXXX XXXXX correct, this is not not normal. It should light once, stay on all they way until slightly above the set temp, stay off until 20-30 below set temp and repeat. When it is first lighting, how long is it staying on before, going off and lighting agin?
There id one computer board that controls this called the DSI board. It must be at fault for symptoms like this. How old is the unit? IS it under warranty?
6years old so no warranty,there's no thermal coupler somewere causing this?
There is the board, the wire to and the ignitor (sparks, also is the sensor for if light) The wire to and the valve (opens the gas). If you had an issue with any of these it would cause it not to light or get fire at all (saftey reasons). the fact that it works just at the wrong times tells me it has to be the DSI board. I have had issues with these in the field as well. If you are tool handy, the board isn't that hard to replace.
is there only one board in this unit and where is it?
It is located on the top under the far right hand side. Remove 2 burners on right hand side, under them is a couple metal covers, under those covers are the electronics. Two boards, one for fans,lights, ect other smaller boar is DSI.
ok thanks what does DSI stand for?
Direct spark ignition
