Product Details

The Rheem-Ruud 42-100491-11 is a genuine OEM start relay designed for use in Rheem, Ruud, Weather King, and Corsaire air conditioning and heat pump systems. This relay is an essential electrical component that controls the startup sequence of the compressor motor.

Key Features:

  • Genuine Rheem-Ruud OEM replacement part
  • Electrical relay switch designed for HVAC compressor applications
  • 60 Hz frequency rating for standard residential and commercial applications
  • Ensures reliable compressor startup in air conditioning and heat pump units
  • Direct replacement for original equipment

Start relays function as electrically-operated switches that open and close circuits within HVAC equipment. In most systems, a low-voltage coil energizes the relay to control a higher voltage circuit that powers the compressor motor. This component is critical for proper system operation and should be replaced with genuine OEM parts to ensure compatibility and reliability.

So happy they had a hard to find part for my Norcold fridge. I chose 2 day shipping - fast and affordable.

Best price and easy checkout

Quick and easy

Nice site

Very easy

The item came in and could have been packaged with more padding as one of the vent shades had a hole in it. Returned it for a replacement which I have not received yet and had the other item picked up. We will see how the next set of visors come in.

Fast ship

Quick and easy! Hopefully, the shipment is the same!!!

Great experience fast shipping
