Thank you! Your furnace board works perfectly!! If you ever come across a 5 burner York Diamond 80 heat exchanger, I would love to keep this beauty running another 30 years!!
Direct replacement, worked right after installation and is still working on my york diamond 80 system. 3 weeks strong so far. Old board was shorted on the backside, diagnosed before seeing the damage. Inducer would not receive power when system called for heat resulting in pressure switch stuck open. Inducer showed resistance (not OL) and also spun freely, so took a chance and got board and problem solved.
White Rodgers Furnace Control Circuit Board 50A50-241 YORK 031-01266-000
Installed in like 10 minutes, worked perfectly, ignited and soon as power was applied and this board fixed my issue of the gas valve not opening or something similar were the gas would never come on just the blower but the board fixed it good as new. Would recommend this vendor and this product to all parties in need.
