90340 – RELAY (DPDT, 24V COIL)

If your AC clicks but doesn’t start, or the outdoor unit won’t turn on at all, the contactor is the first thing to check. 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 DPDT (double-pole, double-throw) relay is one of the most common types.

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

Replaces: 90340, 38276, 42-TLR340, 92840, P-8-8479, P88479, PR340

Fits: Goodman: DGHA125A020CN; also fits most furnaces and air handlers requiring a 24V DPDT fan relay
