1P32A24V – CONTACTOR (SCREW TERMINALS)

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. This is the OEM Rheem single-pole 32A contactor with screw terminals, used in many Rheem and Ruud outdoor units. Plug-in contactors won’t work here — you need the screw terminal version.

Replaces: 42-109499-24, 42-102664-24, 17311, 425069, D157567P02, HN51KC024, XMCO-321-EBBCVN, XMC0-321-EBBC

Fits: Rheem and Ruud AC condensers and heat pumps using a single-pole screw-terminal contactor

How do I know if my contactor is bad?

Pitted or burned contacts, a buzzing sound when the AC tries to start, or the contactor sticking closed (AC runs constantly, never cycles off). Pull the front cover and look at the contacts — if they're black or pitted, replace it.

Can I use a higher amp rating?

Yes. Going up in amps is fine (40A replacing a 30A is safe). Coil voltage MUST match exactly — 24V coil only goes in 24V circuits.

2-pole vs 3-pole — which do I need?

Count the thick wires hitting the line side (top). 2 fat wires = 2-pole (residential split-system). 3 fat wires = 3-pole (3-phase commercial). Most residential is 2-pole.

How long does a contactor last?

5-10 years typical. Insects, dust, and short-cycling shorten the life. If you find ants or wasps nesting in your condenser, that often kills contactors fast.
