Kenmore Refrigerator Will Not Start — Electrical Diagnosis Guide

A Kenmore refrigerator that will not start can mean two very different conditions: the entire unit is dead (no lights, no fans, no compressor — nothing), or the unit has power but the compressor does not run (lights work, fans may or may not run, but no cooling). These are fundamentally different problems requiring different diagnostic paths. Additionally, the platform (106-series Whirlpool vs 795-series LG) determines which specific components are most likely at fault.

Completely Dead — No Power at All

If nothing works — no interior light, no display, no fan noise — the issue is upstream of the refrigerator's internal components.

Check the Power Supply First

1. Verify the outlet. Plug a lamp or phone charger into the same outlet. If it does not work, the outlet has no power. Check your home's electrical panel for a tripped breaker (dedicated 20A circuit for the refrigerator is standard in homes built after 1995).
2. Check the power cord. Older Kenmore refrigerators (pre-2005) sometimes have the power cord routed behind the unit where it can be pinched or damaged when the unit is pushed back against the wall. Pull the unit forward and inspect the cord for damage.
3. Check GFCI outlets. Some kitchen remodels put the refrigerator on a GFCI circuit. If the GFCI has tripped (common after a power surge or moisture event), it cuts power to the outlet. Reset the GFCI button.

If the outlet has power and the cord is intact, but the unit is completely dead, the issue is internal.

106-Series (Whirlpool) — No Power Internally

On 106-series Kenmore units, the power cord connects to a terminal block inside the rear compressor compartment. From there, power routes to the main control board (on electronic models) or directly to the thermostat (on mechanical models). A completely dead 106-series unit with confirmed outlet power is typically:

• Burnt terminal block connection (the power cord connection at the back of the unit). Common on units 15+ years old where oxidation creates a high-resistance joint that eventually arcs and burns open. Inspect the terminal block for char marks or melted plastic.
• Failed electronic control board (on models with electronic temperature controls). The board is the first power-distribution point. If it fails in a mode where its internal relay does not close, nothing downstream gets power.

Parts Cost: $10-20 (terminal block) / $35-80 (control board) Professional Repair Cost: $100-250

795-Series (LG) — No Power Internally

Kenmore 795-series units route power through the main PCB immediately. If the main board fails completely (for example, a fused link on the board blows due to a power surge), the entire unit goes dead — no display, no lights, nothing.

Diagnostic: If the unit went dead during a thunderstorm or power surge, the main PCB is the prime suspect. LG part EBR78940602 or model-specific equivalent.

Parts Cost: $120-250 Professional Repair Cost: $250-400

Has Power But Compressor Won't Run

This is the more common "won't start" scenario. Interior lights work, the display is active (if equipped), but the compressor does not engage and no cooling occurs.

106-Series (Whirlpool) — Compressor Won't Start

Start Relay Failure (45% of Cases)

The most common cause of a 106-series Kenmore that has power but won't cool is a failed start relay. The relay (Whirlpool part W10613606, approximately $15-30) plugs directly onto the compressor pins and provides the starting current surge the compressor motor needs to overcome static friction.

When the relay fails, you hear the click-buzz-click pattern every 2-5 minutes: the compressor attempts to start (click), cannot overcome starting torque and draws locked-rotor current until the thermal overload trips (buzz for 2-5 seconds), the overload cools and resets (click), and the cycle repeats.

Quick test: Unplug the fridge. Remove the rear access panel. Pull the start relay off the compressor terminals. Shake it — if you hear loose parts rattling inside, it has failed mechanically. Also check for burn marks or melted plastic.

Parts Cost: $15-30 Professional Repair Cost: $90-150

Compressor Thermal Overload Tripped (20% of Cases)

If the compressor was running normally and then stopped (perhaps after the kitchen got very hot, or after the door was left open causing extended run time), the thermal overload protector on the compressor may have tripped. This is a self-resetting device, but it can take 30-60 minutes to cool enough to reset.

Diagnostic: Wait 60 minutes with the unit unplugged. Plug back in. If the compressor starts normally, it was a thermal overload trip from extended operation. If this recurs frequently, the compressor is working too hard — check for dirty condenser coils or low refrigerant charge.

Thermostat/Control Not Calling for Cooling (15% of Cases)

On 106-series units with mechanical thermostats (the numbered dial inside the fresh food section), the thermostat contacts close when the compartment temperature exceeds the setpoint, sending power to the compressor circuit. If the thermostat fails open, it never sends the run signal.

Diagnostic: Turn the temperature dial from its lowest setting to its highest. You should hear a click as the contacts close. No click at any setting means a failed thermostat. On electronic models, the board serves this function — a failed board relay produces the same symptom.

Parts Cost: $25-55 (thermostat) / $35-80 (electronic board) Professional Repair Cost: $120-220

Compressor Motor Winding Failure (15% of Cases)

After 12-20 years, the compressor motor windings can develop open or shorted conditions. An open start or run winding prevents the motor from energizing at all. Shorted windings trip the overload immediately.

Diagnostic: With the start relay removed, use a multimeter to check resistance between the three compressor pins (Common, Start, Run). The sum of Start-to-Common and Run-to-Common should approximately equal Start-to-Run. Any open reading (infinite resistance) indicates a failed winding. Any reading to the chassis ground indicates a winding-to-case short (dangerous, do not operate).

Compressor replacement on a 106-series unit older than 12 years is rarely cost-effective. At this age, the unit is approaching end of service life and a replacement refrigerator may be the better investment.

Professional Repair Cost: $500-850 (compressor replacement)

Capacitor Failure (5% of Cases)

Some 106-series Kenmore models use a separate start capacitor in addition to the relay. The capacitor provides extra starting torque for the compressor motor. When it fails, the compressor hums briefly but cannot break free and trips on overload — similar to a relay failure but with the relay testing good.

Parts Cost: $10-30 Professional Repair Cost: $90-160

795-Series (LG) — Compressor Won't Start

Linear Compressor Control Circuit Failure (40% of Cases)

The LG linear compressor in 795-series units is not powered by a simple relay like the Whirlpool rotary compressor. Instead, it uses an inverter-type controller built into the main PCB that generates the oscillating drive signal. If this controller section fails, the compressor receives no drive signal and remains silent.

Diagnostic: The unit has power (display works, lights on) but is completely silent — no compressor vibration at all. No error code may display because the board is not detecting a fault in the circuit (it simply is not generating the drive signal).

Parts Cost: $120-250 (main PCB) / $400-700 (compressor if mechanical failure) Professional Repair Cost: $250-1,100 depending on component

Error Code Lockout (30% of Cases)

The 795-series control board can enter a fault lockout mode that prevents compressor operation after detecting specific errors (Er gF ground fault, repeated compressor overcurrent trips). The display may or may not show the error code depending on model. Power cycling (unplug for 5 minutes) may clear the lockout if the underlying condition has resolved.

Compressor Winding/Mechanical Failure (30% of Cases)

Same diagnostic as 106-series but on the LG linear compressor platform. Check for class action warranty coverage on units manufactured 2014-2020.

Step-by-Step Diagnostic Procedure

1. Is the outlet live? Test with another device. Check breaker panel.
2. Any signs of power? Interior light, display, fan noise?
3. If no power at all: Check power cord, terminal block (106) or main PCB (795).
4. If power but no compressor: Listen for click-buzz-click pattern (106 start relay failure). Listen for total silence (795 control board failure). Listen for brief hum then stop (thermal overload or capacitor).
5. Check error codes (795 only): Press Refrigerator + Freezer for 3 seconds.
6. Test start relay (106): Remove and shake. Inspect for burns.
7. Test compressor windings: Multimeter on three pins after removing relay.

FAQ

Q: My Kenmore makes a clicking sound every few minutes but won't start. What is it?

That is the classic click-buzz-click pattern of a failed compressor start relay on a 106-series (Whirlpool) unit. The compressor attempts to start, fails, and the thermal overload trips and resets repeatedly. This is a $15-30 part that takes 10 minutes to replace.

Q: My Kenmore stopped working after a power outage. Should I wait or call for repair?

Wait 1-2 hours first. The compressor has a built-in restart delay after power interruption. If the unit does not resume normal operation within 2 hours, a component likely failed during the outage event (power surge damage to control board or start relay).

Q: Can a Kenmore refrigerator be worth repairing if the compressor is dead?

For 106-series units under 10 years old, yes — compressor replacement is $500-850 vs $1,200-2,500 for a new unit. For 795-series units, check warranty first — many LG-platform compressors are covered under the class action settlement regardless of unit age within the covered date range.
