Maytag Refrigerator PBB2255GES Won't start or doesn't start

The Run Capacitor is an OEM part for Whirlpool refrigerators. It is responsible for helping the compressor motor start and run efficiently by providing an extra electrical boost. This component ensures that the refrigerator operates smoothly and maintains the correct temperature by stabilizing the compressor's performance.

Causes of a bad run capacitor can include electrical surges, age-related wear, or overheating. When the capacitor fails, the compressor may struggle to start or run continuously, leading to inefficient cooling or a non-functional refrigerator.

Symptoms of a bad run capacitor include:

• The refrigerator not cooling properly
• The compressor not starting or running intermittently
• Unusual clicking noises from the refrigerator

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This overload/relay is the compressor start device for select refrigerators. It provides the brief start assist and overload protection the compressor needs to start and run safely, helping restore consistent cooling when the original part fails.

• Supplies the momentary start pathway for the compressor, then disengages
• Opens on overcurrent/overheat to protect compressor windings
• Failure may present as clicking near the compressor, warm temps, compressor not starting, or intermittent cooling
• Visible heat damage or a rattling start device can also indicate replacement

• Disconnect power and remove the rear lower access panel to reach the compressor area
• Note wire locations; pull the old start device straight off the compressor pins—do not bend the terminals; transfer any harnesses
• Reinstall the cover, restore power, and verify the compressor starts

This is the mechanical cold-control thermostat for the freezer. It senses temperature and switches the cooling system on and off to maintain your selected setting, restoring steady freezer temps and normal compressor cycling.

• Regulates freezer temperature by opening/closing electrical contacts to control cooling
• Symptoms of a failing control include freezer too warm or too cold
• Unit runs constantly, won't start, or won't shut off at set point
• Temperature knob feels unresponsive or no distinct "click" when turned

• Disconnect power before servicing
• Access the control housing; note wiring and transfer leads one at a time
• Route the sensing tube exactly as original; do not kink, pinch, or cut it
• Set to a mid setting after install and allow up to 24 hours for temps to stabilize
