This compressor start device kit helps your refrigerator or freezer's compressor start reliably each cooling cycle. Replacing a weak or failed start device can restore cooling performance and stop repetitive clicking or brief humming when the compressor tries to start.

• Powers the compressor's start winding to initiate start-up, then disengages
• Supports consistent compressor starts to maintain proper temperatures
• Common symptoms of failure: unit warm, compressor not running, rapid clicking from rear, humming then shuts off
• May accompany signs like heat damage or a burnt odor at the old device

• Unplug the appliance before servicing; allow components to cool
• Located on the side of the compressor behind the rear access panel
• Photograph wiring and compressor pin layout; transfer wires one at a time and seat the device fully on the pins
• If your unit uses a separate run capacitor, reconnect it exactly as originally wired
