90370 – RELAY (SPDT, 24V COIL)

A fan relay controls when the indoor blower motor turns on and off. If the blower won’t start, or runs nonstop and never shuts off, a failed relay could be the cause. This 24V SPDT (single-pole, double-throw) relay is a common universal type used in many residential furnaces and air handlers.

Specs: 24V coil, SPDT (single-pole, double-throw), quick-connect terminals, multi-position mounting

Replaces: 90370, PR370

Fits: Most furnaces and air handlers requiring a 24V SPDT fan relay
