Hello,My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.
is there a particular blink pattern on the circuit board light?
Right now it's just the fast continues blink, call for heat.
and is the unit currently heating?
Flame on and main blower running?
Blower is running but it's pushing cold air.
Blower is running but it's pushing cold air. Code now is blinking 2 times.
Please do this:
Turn off the furnace at thermostat.
Wait until no operation
Turn thermostat up
Then tell me the order in which things happen....
exhaust fan, ignition, blower, flames out/on...etc
Flames won't kick in, furnace keeps turning off then on to retry.
Did you hear the gas valve click twice about a minute after the exhaust fan started?
No I didn't. Blower kicked on but it's cold air.
Ok you likely have a bad ignitor.
Are you interested in locating and fixing yourself?
see this pic
can you remove the ignitor and tell me if there is a fine white line across it?
Mine doesn't look like that? It's a XR90
it all depends on the year. XR90 is like saying Camaro...but the year is what determines format.
I would need a model number or pic of your unit..but the end result is the ignitor is always in front of the burner...whether high,low, behind a plate etc..
