Have HVAC Questions? Ask an HVAC Expert for Answers
Hello,My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.
when you need heat, doe the heat function work but the main blower just never shuts down?
Yes...but the light remains solid? lit or off?
If the light remains solid
The blower runs continuous
Heat does not work = bad circuit board.
Do you have 24v at R and C on board?
The issue can also be caused by a glitch that took out thermostat, yet seized blower relay.
I would jump R and W at board for a direct call for heat. The same result will apply though if it heats and blower will not stop...=new board
And if it heats with r jumped to w - new thermostat too
no problem, just respond when you have further info.
Keep this on your end until ready.
Jump R to W means connect the 2 either twist togther or connect with small jumper
if main blower stopped and the exhaust did not start...and the light remains solid is indicative of a bad circuit board
Then some info is not correct.
Did the exhaust fan start when r to w connected?
You say blower stopped when r to w connected..this means there is not an open safety as R would have no power.
Light is solid...this means no fault,,which means heat or cool should work..and if they do not a code would flash
What is current status?
ok so now we have seen blinking....what is the blink pattern?
And we did a glow from ignitor but not ignition?
Or do you prefer to close this and call for service?
I cannot schedule from this venue.
You would need to contact a local Bryant, Carrier or Payne dealer.
Any of these brands will have the necessary parts and training to take care of you
Yes I am.
