Furnace control board pricing
Main floor furnace not operating due to bad furnace control board. Will be ordering from Apex. Waiting to find out if it’s still under manufacturers warranty and price and availability for control board.
Customer said over the weekend when temperatures dropped below freezing that he had no display on his thermostat and the condensation pump was constantly running I informed him that was most likely because the clear tubing outside was frozen so we re-routed his condensation line to tap into some plumbing inside the mechanical room to finish the problem from happening in the future and everything is running normal at this time
Replaced main limit switch. System is working properly at this time
The Control board and high limit lower housing is bad , will not allow the system to run correctly and properly
