Product Overview
The 118000001 is a RetroAire relay that switches power in the control circuit of RetroAire PTAC units. In the circuit, it switches power to a connected load (such as a blower, valve, or accessory circuit) when energized by the unit's control board or safety switches. It carries the load current so the lower-power control signal is not run directly through the switched device.
This relay fits RetroAire PTAC control circuits; see the Fitment panel for the full model list. It is also sold and searched under the number 22786-70; confirm wiring against your unit's control diagram before ordering.
It is supplied ready to install as a like-for-like replacement. It ships as a standalone unit that wires into the existing control harness using the factory connector.
Replacing this part: disconnect power to the unit before opening the control panel. Match the new relay's connector and mounting orientation to the original, and have a qualified technician verify proper operation after installation.
