Roper Refrigerator RT18ECRHW00 Won't start or doesn't start

The Whirlpool Defrost Timer is an OEM replacement part for Whirlpool refrigerators. The defrost timer regulates the automatic defrost cycle, which prevents ice buildup on the evaporator coils in the freezer compartment by sending a signal to the defrost heater to turn on and melt any ice buildup on the coils. 

Causes of a bad defrost timer can include mechanical wear over time, electrical failures, or internal component damage. Prolonged usage and voltage spikes can also affect the timer's functionality.

Symptoms of a bad Defrost Timer include:

• Excessive frost buildup in the freezer compartment
• The refrigerator or freezer not maintaining the set temperatures
• Unusual noises coming from the appliance 
• The appliance running continuously without cycling off

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

The Thermostat is an OEM part for Whirlpool refrigerators. It regulates the temperature inside the refrigerator and freezer compartments by controlling the cooling cycles, ensuring food and beverages are kept at the desired temperature.

Over time, thermostats can fail due to electrical malfunctions, wear and tear, or exposure to fluctuating temperatures. A faulty thermostat can disrupt the cooling process, leading to inconsistent temperatures.

Symptoms of a bad thermostat include:

• Refrigerator or freezer too warm or too cold
• Inconsistent temperature maintenance
• Refrigerator running continuously or not at all
• Spoiled food due to improper cooling

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

This compressor overload is a thermal protector that opens the circuit if the compressor overheats or draws excessive current. Replacing a failed overload restores reliable starts and helps prevent compressor damage when your refrigerator won't cool.

• Protects the compressor by interrupting power during overheat/overcurrent conditions
• Common symptoms: refrigerator not cooling, compressor won't start, repeated clicking or brief hum then shutoff
• Mounts on the compressor terminal and works alongside the start relay on applicable models
• Built for proper fit and dependable operation in the start circuit

• Unplug the refrigerator and remove the rear access panel to reach the compressor
• Note wire positions; pull the old overload straight off the compressor pin
• Push the new overload fully onto the correct terminal and reconnect wiring/terminal cover
• Restore power and verify the compressor starts without repeated clicking
