Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater
BLOWER FAN WONT SHUT OFF WHEN THERMOSTAT IS OFF. ALSO COOLING MODE TURN ON. I CAN PUSH CONTACTOR IN AND COMPRESSOR WILL COME ON.
I have a honeywell blower that runs all time it won't shut off unlees I manually shut it off. How do I reset the fan limit control switch so the fan will come on only when the furnace ignitions ignites. Any suggestions.

The compressor coming on when the contact is pushed is o.k. they all do that. As for the blower fan not shutting off, some brands (Payne for example) the heating fan relay is a n.c. (normally closed ) relay. so if the time delay relay or thermal link are bad or not connected, the fan will blow even when it is turned off.
