Viking Refrigerator Clicking Sound from Bottom Grille:... | appliancefaults.com

Technical Background:

Viking refrigerators use a Main Control Unit (MCU) to manage various functions. The MCU sends voltage signals to relays and solenoids to control components like the compressor, defrost system, and ice maker. A clicking sound usually indicates a relay or solenoid rapidly switching on and off.

Symptoms:

US homeowner observes a clicking sound coming from the bottom grille area of their Viking refrigerator.

Possible Causes:

Compressor relay cycling
Defrost timer malfunction
Condenser fan motor obstruction or failure
Start relay/overload failure
Ice maker water valve cycling (if near bottom)
Damper control issue

Solution:

1

Unplug the refrigerator or turn off the dedicated breaker in the breaker panel.
2

Remove the bottom grille (usually Phillips head screws or spring clips).
3

Inspect the condenser fan. Check for obstructions (debris) and ensure the fan spins freely. If obstructed, remove the debris.
4

Check the compressor relay/overload. Using a multimeter, test for continuity. If open, replace the relay/overload.
5

Listen closely to pinpoint the source of the clicking. If it's the defrost timer (often located near the bottom), check its operation. Timers are generally non-serviceable. Replacing is the usual solution.
6

If the clicking is coming from the ice maker water valve, test its solenoid with a multimeter. Look for approximately 300-500 ohms. If open, replace the valve.
7

Plug the refrigerator back in or turn the breaker back on and monitor for normal operation.

Safety Warning:

Always disconnect power (LOTO - Lock Out Tag Out) before working on any electrical appliance. The refrigerator contains 120V AC components. Exercise extreme caution to avoid electrical shock.

Prevention:

Regularly clean the condenser coils (located behind the bottom grille) every 6 months using a vacuum cleaner with a brush attachment. This prevents overheating and prolongs the life of the compressor and condenser fan motor.

Expert Tip:

Many Viking refrigerators have a service mode accessible through the control panel. Consult the service manual or search online for the specific model's service mode entry sequence. This mode allows for diagnostics and component testing.

Frequently Asked Questions

•Where exactly is the compressor relay located on my Viking refrigerator?

The compressor relay is usually mounted directly on the compressor itself, or nearby. It's a small, rectangular component with several wires connected to it. You'll likely need a 1/4-inch nut driver to remove the cover.

•How do I test the defrost timer?

Some defrost timers have a manual advance knob. You can slowly turn this knob until the refrigerator goes into defrost mode (compressor stops, defrost heater activates). If it doesn't advance or make any clicking sounds, it's likely faulty. You can also test the continuity of the timer contacts, but this requires a wiring diagram.

•What is the correct replacement part number for the condenser fan motor?

The correct replacement part number for the condenser fan motor will be specific to your Viking refrigerator model number. You can find this number on a sticker inside the refrigerator compartment, usually on the side wall or ceiling. Once you have the model number, you can search for the condenser fan motor part number online or contact a Viking appliance parts supplier.
