York Stellar furnace blower problem
I have a 19 year old York Stellar furnace. Model P1UCD12N04601B 57,000 btu's. This unit was salvaged from a military housing complex that closed in 1990. The unit shows very little wear. All the parts look new. The unit sat no operational for nearly 16 years. I removed the unit from the house myself.
When the unit starts up the exhaust blower is the first to go on. This activates the ignitor via a vacume switch, ignitor reaches temp and gas kicks on. The unit heats up then the updraft blower starts. This is all normal operation to this point.
After about 1 to 2 minutes of the blower starting the blower kicks off and continues this 1 to 2 minute cycle until the thermostat reaches temp. AM startup of the heater usually runs about 1/2 hour. After the burners go off the fan continues the off and on cycle until the unit cools down. Is this a relay problem in the control panel at the blower compartment or something else? I really need some advice before my blower burns out from all the starting and stopping.
Thank You
