Diagnostic Steps Before Replacing
Before replacing the control board, verify:
24 VAC between R and C
Proper 120 VAC line voltage
Transformer output
Thermostat is calling for heat/cooling
Pressure switch operation
Limit switch continuity
Rollout switches reset and closed
Hot surface ignitor resistance
Flame sensor cleanliness and flame signal
Gas valve coil continuity

Blower motor and capacitor condition
Wiring harnesses fully seated
Relay outputs functioning correctly
If all external components test properly and the board fails to energize the inducer, ignitor, blower, or gas valve, the control board is likely defective.
