Kelvinator Refrigerator Relay, Overload, Capacitor

The Compressor Run Capacitor is an OEM replacement part for Frigidaire refrigerators. This electrical component is essential for providing the necessary torque to start and maintain the operation of the compressor motor, which is responsible for cooling the refrigerator.

Symptoms of a failing compressor run capacitor include:

• The refrigerator not running or cooling properly
• The compressor failing to start or running intermittently
• Humming or buzzing noises coming from the compressor area

Causes of needing to replace the compressor run capacitor can include normal wear over time, exposure to high temperatures or electrical surges, or physical damage to the capacitor itself.

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore refrigerator models. 

This compressor start device briefly energizes the compressor's start winding to get it running, then disengages automatically. Replacing a weak or open PTC can restore cooling and stop the repeating hum-click from the compressor area.

• Provides the initial boost for the compressor to start, then opens as the PTC warms
• Helps the compressor start reliably on each cooling cycle
• Works with the compressor's overload protector to safeguard the motor circuit
• Common symptoms of failure: not cooling, compressor won't start, rapid clicking or hum-click every few minutes, intermittent cooling after power cycling

• Disconnect power and pull the unit forward to access the compressor compartment
• Remove the start-device cover; note wire positions
• Pull the old start device straight off the compressor terminals; avoid bending the pins
• Align the new device with the C–S–R terminals in the same orientation, push on fully, reconnect wires, reinstall cover, and restore power
• Inspect the mating overload protector and terminal connectors for heat damage before reassembly

This compressor start relay (PTC) briefly powers the compressor's start winding to ensure reliable start-up. Replacing a failed relay can stop repeated clicking and help a non-starting compressor restore normal refrigerator cooling.

• Provides a timed, resistance-based boost to the compressor's start winding, then drops out of the circuit
• Common symptoms: compressor hums then clicks off, frequent clicking from the rear, warm fridge/freezer, intermittent cooling
• Mounts directly on the compressor terminals; works with the separate overload protector and, if equipped, a run capacitor
• Visible signs of failure may include heat damage, burnt odor, or loose/rattling pieces inside the old relay

• Unplug the refrigerator and remove the lower rear access panel to reach the compressor
• Note wire routing and orientation; transfer any harness/retainer and seat the relay fully on the compressor pins
• If a run capacitor is present, discharge it before handling and reconnect to the same terminals
• Inspect the overload and connectors; replace any heat-damaged components

This run capacitor helps the refrigerator compressor start and run smoothly, restoring normal operation when a weak or failed capacitor causes the compressor to struggle. Replacing a faulty capacitor can reduce humming and improve cooling performance. What it does:

• Provides continuous phase-shift to the compressor motor for stable running.
• Helps maintain proper compressor speed and efficiency during operation.
• Commonly replaced when the compressor hums, won't stay running, or cooling is inconsistent.
• Reduces risk of repeated motor cycling caused by a weak or open capacitor.

• Always disconnect power to the appliance before accessing electrical components.
• Discharge the capacitor before handling; capacitors can hold a charge even when powered off.
• Observe terminal orientation and mounting location; replace with the same type and ratings.

This Temperature Controller regulates cooling by switching power to the compressor and related circuits to hold the set temperature. Replacing a failing controller restores accurate temperature control and reliable operation. What it does:

• Cycles cooling components to maintain the temperature you set
• Helps keep cabinet temperatures consistent for proper food storage
• Coordinates on/off operation to prevent overcooling or warm conditions
• Common failure symptoms: too warm or too cold, runs constantly or won't start, control/dial unresponsive

• 1 temperature controller

• Disconnect power before servicing—this is a line-voltage control
• Access the control area, label or photograph wire positions, and move wires one at a time to the new controller
• Reuse existing mounting hardware and any knob/overlay as applicable
• After install, set to mid setting and allow up to 24 hours for temperatures to stabilize

This electronic control board is the refrigerator's main circuit board that manages temperature, defrost and user controls—restoring responsive control functions and resolving erratic or non-working control behavior. What it does:

• Controls compressor, fans and defrost cycles by sending signals based on sensor inputs
• Manages user interface commands and display response
• Can stop fridge cooling or cause incorrect temperatures when failing
• May cause intermittent operation, no display response, or failure to complete defrost cycles

• Disconnect power to the appliance before starting any work to avoid electrical shock
• Handle the board by its edges and avoid touching components or connector pins
• Verify connector orientation and seating; replace exactly like-for-like to ensure compatibility
