Overview
This genuine OEM single-pole contactor (part number 14306504) is the switching relay that powers the compressor and condenser fan in the ICP / Tempstar / Heil YD018GA heat pump. It is a 1-pole device rated at 14 amps with a 24-volt control coil. When the thermostat sends a 24V signal, the coil pulls the contacts closed and sends line voltage to the compressor and outdoor fan motor; when the call ends, the contacts open and de-energize the unit. Contactors are high-wear components — the contacts arc every time they close — so they pit, weld, or burn over time. A failed contactor is one of the most common no-cool / no-heat service calls. Typical symptoms include a humming or chattering outdoor unit, contacts that stick closed (unit won't shut off), contacts that won't pull in (unit won't start), and visible pitting or burning on the contact points.

Compatibility

Installation Guide
- Safety First – Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access – Remove the condensing unit service panel to expose the control box.
- Document – Photograph all line, load, and 24V coil wiring before disconnecting.
- Remove – Label and disconnect each wire, then unscrew the old contactor from its mounting bracket.
- Install – Mount the new contactor, then reconnect line, load, and coil wires exactly per your photo.
- Test – Restore power, call for cooling/heating, and confirm the contacts pull in cleanly and the unit starts.
Signs You Need a Replacement
- Outdoor unit hums or chatters but won't start.
