you may want to check the little port view window on this furnace....fixed tons of them...when operating the little window is making a clicking noise just touch it ..it will stop...ben srGreetings...long time lurker, first time poster.
I have (as mentioned in the subject line) a Tempstar DC90 furnace...and it has an "issue." When producing heat, the "smart" gas valve has an intermittent (but frequent) clicking problem.
Using the gas shutoff valve, I can marginally increase the gas flow to the smart valve, and the clicking will stop...but eventually, the flame rollout switch will engage, resulting in loss of flame.
By the same token, a very small change of inlet flow will allow the furnace to produce heat day in and day out...but the gas valve will return to it's pattern of clicking. Thoughts? Suggestions?
My thanks for your kind consideration.
