Roper Refrigerator RT12DKYEW00 Won't start or doesn't start

The Relay and Overload Kit is an OEM replacement part for Whirlpool refrigerators. It is an essential component of the refrigerator's electrical control system, responsible for powering components and protecting circuits from overload. 

Causes of a bad relay and overload kit include circuit malfunctions, failed or worn-out components, or improper installation. 

Symptoms of a bad relay and overload kit are:

• Refrigerator not cooling or icing 
• Components like lights or fans not working
• Buzzing or humming noises from the electrical control area
• Repeated blown fuses 

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

This cold control thermostat regulates your refrigerator's temperature by cycling cooling on and off based on air temperature at the sensing bulb. Replacing a worn control restores accurate settings and consistent cooling performance. What it does:

• Monitors compartment temperature via a capillary sensing bulb
• Opens/closes electrical contacts to start and stop the compressor (and related cooling circuits)
• Helps maintain the temperature you set on the control dial
• Failure symptoms include: unit too warm or too cold, runs continuously, won't start until the knob is moved/tapped, or erratic temperature swings

• 1 thermostat

• Disconnect power before servicing; wear cut-resistant gloves
• Note wire positions or take a photo; transfer the dial/shaft and any mounting hardware from the old control if reused
• Route the capillary bulb exactly as original; do not kink, pinch, or cut it; secure with existing clips
• After install, set to a mid setting and allow up to 24 hours for temperatures to stabilize
