Whirlpool Refrigerator Won't Start or Clicks — 5 Compressor Relay Failures & Fixes

Your Whirlpool fridge stops cooling overnight. You hear a faint click every few minutes, but the compressor never kicks on. You open the freezer and everything's starting to thaw. This clicking-without-starting scenario points straight to a failed compressor start relay — the little component that gives your compressor the electrical boost it needs to fire up.

The 2188830 start relay and overload protector work as a team. The relay delivers a surge of power to get the compressor motor spinning, then drops out once it's running. The overload protector acts as a safety switch, shutting everything down if the compressor draws too much current. When either component fails, your fridge goes silent or clicks uselessly.

Quick Symptom Check

Your compressor relay has likely failed if you notice:

• Clicking every 2-5 minutes — relay trying to engage but failing
• Complete silence — no compressor sound, but lights work
• Warm fridge, frozen food thawing — compressor not running at all
• Compressor runs briefly then stops — overload protector tripping
• Burning smell near bottom back — relay overheating before failure
• Compressor hot to touch but not running — locked rotor or bad relay

Cause #1: Burnt-Out Start Relay Contacts (65% of Cases)

The relay contains electrical contacts that close to send power to the compressor's start winding. After thousands of startup cycles, these contacts develop carbon buildup or weld themselves together from electrical arcing.

Diagnosis: Remove the relay (it's the black plastic box attached to the compressor at the back bottom of your fridge). Shake it gently near your ear. A working relay rattles — you'll hear the internal contact moving freely. If you hear nothing or it sounds stuck, the contacts have failed. This is your problem 65% of the time.

The fix: Replace the relay. No repair possible — it's a sealed unit. The 2188830 fits Whirlpool models like GS6SHAXKS01, ED5VHGXMQ10, ED5FHGXKQ02, and dozens more. Cost: $43.99. Takes 15 minutes with just a 1/4" nut driver.

Why it fails: Normal wear. Every time your compressor cycles on (4-8 times per hour depending on usage), those contacts open and close. After 5-7 years, they're done.

Cause #2: Tripped Overload Protector (20% of Cases)

The overload protector is a bi-metal switch that monitors current draw. When the compressor pulls too many amps — usually because it's struggling due to dirty condenser coils or a failing compressor — the overload heats up and breaks the circuit.

Diagnosis: If your compressor tries to start, hums loudly for 3-5 seconds, then clicks off, the overload is doing its job. The compressor housing will feel hot. Wait 30 minutes for everything to cool, then try starting the fridge again. If it runs briefly then stops again, you have an overload issue.

The fix: First, clean your condenser coils thoroughly — if they're clogged, the compressor works harder and draws more current. If the overload keeps tripping after cleaning, replace the relay/overload assembly (they come together as the 2188830 unit). If it still trips with new parts, your compressor itself is failing — that's a much bigger job.

Typical scenario: Works in winter, starts tripping in summer when ambient temps rise. The extra heat pushes the already-struggling system over the edge.

Cause #3: Corroded Electrical Connections (10% of Cases)

The relay plugs onto three metal pins on the compressor. These connections can corrode from humidity in the compressor compartment, especially in garages or basements.

Diagnosis: Pull the relay off and inspect the three pins on the compressor. Look for green corrosion, white crusty buildup, or burnt marks. Check inside the relay socket too — the metal contacts should be shiny.

The fix: If the pins show light corrosion, clean them with fine sandpaper or a wire brush. Spray with electrical contact cleaner. If the pins are heavily pitted or burnt, you'll need a new relay anyway — but also consider whether moisture is getting to your compressor compartment. Fix any water leaks or improve ventilation.

Cause #4: Wrong Relay Installed (3% of Cases)

Not all compressor relays are universal. Using the wrong one can cause immediate failure or intermittent operation. This happens after a previous repair where someone grabbed whatever relay fit physically.

Diagnosis: Check the model number stamped on your current relay. Cross-reference it against your fridge model. The 2188830 replaces part numbers AP3885081, PS993073, 2220475, and 8201786 — but only for specific Whirlpool, Kenmore, and KitchenAid models.

The fix: Verify compatibility. Use your fridge's full model number (inside the fresh food section on the left wall) to confirm the 2188830 is correct. If you have an ED5GTGXNQ00 or ED5RHEXNL00, you're good. Installing the wrong relay won't just fail — it can damage your compressor.

Cause #5: Failed Compressor Masquerading as Bad Relay (2% of Cases)

Sometimes the compressor itself seizes or develops a short circuit in the start winding. This looks identical to a bad relay — clicking, no start, or immediate shutdown.

Diagnosis: This is the expensive scenario. With the relay removed, use a multimeter to test continuity between the compressor pins. You should read 2-4 ohms between the start and common pins, and 1-3 ohms between run and common. Any reading over 10 ohms or infinite resistance means an open winding. Zero ohms to ground (the compressor case) means a shorted winding.

The reality check: If your compressor tests bad, replacing the relay won't help. Compressor replacement runs $400-800 in parts and labor. At that point, you're making a repair-vs-replace decision on the whole fridge. Get a second opinion before committing.

DIY Relay Replacement Steps

Tools needed: 1/4" nut driver, flashlight, work gloves (compressor may be hot)

Time required: 15 minutes

1. Unplug the fridge. Don't skip this. You're working with live compressor terminals.
2. Pull the fridge away from the wall. You need access to the back lower section.
3. Locate the compressor. It's the black cylindrical component at the bottom. The relay is the small plastic box plugged onto it.
4. Remove the relay cover. Some models have a metal or plastic shield — usually one screw.
5. Pull the old relay straight off. It's friction-fit onto three pins. Rock it gently side-to-side while pulling.
6. Install the new 2188830. Match the pin orientation (there's only one way it fits correctly). Push firmly until fully seated.
7. Replace the cover. Tighten the screw.
8. Plug in and test. The compressor should start within 2-3 minutes. Listen for a solid hum, not clicking.

When to Call a Pro

This is genuinely a DIY-friendly repair. The relay costs $43.99 and takes a quarter hour to swap. Call a tech if:

• Your compressor tests bad (see Cause #5 above) — you're looking at compressor replacement
• The new relay doesn't solve the problem and you've confirmed correct installation
• You smell refrigerant (sweet, chemical odor) — you may have a sealed system leak
• The compressor runs but the fridge still doesn't cool — your problem is elsewhere

A service call for diagnosis runs $80-120. They'll test the compressor, check the sealed system, and give you a real quote. But try the relay first — it solves the problem 85% of the time.

Use your exact model number to verify — it's printed on the white sticker inside your fridge compartment.

Frequently Asked Questions

Can I test the relay myself before buying a new one?

Yes. Remove it and shake it near your ear. A working relay rattles — the internal contact moves freely. No rattle means it's stuck or burnt. You can also test with a multimeter: check continuity between terminals with the relay in different positions (upright vs. inverted). But honestly, at $43.99, if you're diagnosing a no-start condition and the relay is original to a 5+ year old fridge, just replace it.

Why does my compressor click repeatedly but never start?

The relay is trying to engage but either its contacts are burnt out or the overload protector is tripping instantly. This clicking-every-few-minutes pattern is the classic symptom of relay failure. The thermostat keeps calling for cooling, the relay tries to start the compressor, fails, waits for the overload to reset, then tries again. Replace the relay/overload assembly.

Will a bad relay damage my compressor?

A failed relay won't directly damage a healthy compressor — it just prevents it from starting. However, if the overload protector fails in the closed position (rare), it could allow the compressor to overheat. And if you keep running the fridge with a bad relay, the repeated failed start attempts can stress the compressor over time. Replace the relay as soon as you diagnose it.
