Roper Refrigerator RT16DKYKT02 Fridge too warm

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 Run Capacitor is an OEM part for Whirlpool appliances, designed to provide the necessary electrical charge to start and run the compressor motor. This part attaches to the compressor to aids in maintaining a consistent motor speed and ensuring smooth operation. The run capacitor plays a crucial role in the appliance's electrical system, storing and releasing energy as needed to power the motor.

Causes of a bad Run Capacitor include electrical surges, wear and tear over time, or overheating, which can lead to a failure in providing the necessary start-up energy or maintaining motor speed.

Symptoms of a bad Run Capacitor include:

• The appliance does not start.
• The motor shuts off shortly after starting.
• The appliance is humming but not running.
• Increased energy consumption.

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 Evaporator Fan Motor is an OEM replacement part for Whirlpool refrigerators. It is responsible for circulating cold air inside the refrigerator compartment to maintain even temperatures. The evaporator fan motor works continuously to circulate air across the evaporator coil, where it is cooled and distributed throughout the fridge.

Causes of a bad fan motor can include debris accumulation hindering blade spin, failed motor windings from constant operation, or loose wiring connections interrupting power flow.

Symptoms include:

• Warm spots appearing in the fridge or freezer
• Inability to reach temperature set points
• Loud grinding or clicking noises from inside

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

The Defrost Bimetal is an OEM part for Whirlpool refrigerators. This crucial component functions as a safety thermostat in the freezer's defrost system. It is designed to monitor and control the temperature of the evaporator coils during the defrost cycle, preventing them from overheating. By cutting off the defrost heater when the coils reach a certain temperature, the bimetal helps maintain optimal functioning and efficiency of the refrigerator’s defrost system.

Symptoms of a failing defrost bimetal include:

• Build-up of frost on the evaporator coils that does not melt during defrost cycles
• Refrigerator or freezer section getting too warm
• Continuous running of the refrigerator compressor

Causes of bimetal malfunction typically include corrosion, continuous exposure to extreme temperatures, and general wear over time, which can prevent it from responding accurately to temperature changes.

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

The Defrost Heater is an OEM part for Whirlpool refrigerators. This heater turns on during the defrost cycle to melt the frost on the evaporator coils. If you need the defrost thermostat order WP4387490

Causes may include cracked heater elements reducing heat output or open circuit damage limiting functionality over time. 

Symptoms of a faulty heater involve:

• Periodic refrigerator odors
• Prolonged defrost cycles or remaining ice
• Frost and ice buildup beyond normal amounts

This is a genuine Whirlpool OEM replacement this part is also compatible with Maytag, Jenn-Air and some Kenmore models.

This freezer wire harness links the refrigerator's control system to components inside the freezer compartment. Replacing a compromised harness restores reliable electrical connections and can resolve intermittent or dead freezer functions caused by burned, broken, or corroded wiring.

• Routes power and signals between the control system and freezer components
• Supports proper operation of devices such as the evaporator fan, defrost circuit, lighting, or icemaker
• Replaces cut, heat-damaged, or brittle wiring and loose/oxidized connectors
• Typical symptoms: intermittent cooling, components not running, or visible burned/melted connectors

• Disconnect power to the refrigerator before servicing
• Photograph routing and connections; move wires over one-by-one to the new harness
• Seat connectors fully until locking tabs engage; avoid forcing pins
• Route through original clips/grommets and keep clear of sharp edges, hot surfaces, and moving parts

This mechanical thermostat monitors temperature and opens or closes the circuit at a fixed set point to control heat and prevent overheating. Replacing a failed thermostat restores safe operation and consistent performance. What it does:

• Senses surface or component temperature and switches the circuit at a calibrated threshold
• Helps protect heaters, motors, and controls from thermal damage due to over-temperature
• Common symptoms of failure: no heat, shuts off mid-cycle, won't start until cooled, or intermittent operation
• Restores proper temperature control after a thermostat sticks open/closed or drifts out of spec

• 1 thermostat

• Disconnect power at the breaker (and shut off gas, if applicable) before servicing
• Note wire positions and transfer leads one-for-one to the new thermostat
• Mount flush against the sensing surface with original screws/clips; reinstall any insulation or thermal interface material as found
• Correct the root cause (blocked vents, failed fan, restricted airflow, or buildup) before returning the appliance to service
