Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your
issue. First I’ll need some more info so I have a more complete picture of your situation.
What's the model number of your unit? how many times does the red ligth blink before it pauses and repeats?
Not sure what the no is referrinf to. If it's regarding the call prompt, it's automatic I have no control over it. We can continue here.A 2 flash is an open draft pressure switch.
Please be patient. I'm not a machine. It takes a while to type and research your issue.
It seems your model has a centrifigal switch. Is the burner motor running?
If the burner motor runs but the burner doesn't ignite and you get the 2 flash red light then the centrifigal switch has probably failed and needs to be replaced. Glow plug won't work with a bad switch.
It's in the burner attached to the motor. As the motor turns the switch contacts get thrown to the outside rim of the switch where they close the circuit proving the motor is running. Switch is in the motor. Motor part number is ***** listed in the parts list. Contact this online vendor for the part. They'll want model and serial numberhttp://bestbuyheatingandairconditioning.com/index.htm
