The Call
On a Saturday afternoon a homeowner in Coral Springs called us in a difficult situation. Their Whirlpool refrigerator had stopped cooling and was making a clicking sound every few minutes. A repair company had already come out that morning, checked the refrigerator, and told them the compressor was bad and needed to be replaced — but since it was Saturday, they would not be able to get the compressor until Monday. The customer was looking at a weekend with a warm fridge and a large repair bill on the way.
They decided to get a second opinion before agreeing to anything. We were on site within two hours.
What the Clicking Actually Means
A refrigerator that clicks every 3–5 minutes and has stopped cooling is one of the most recognizable patterns in appliance repair. The compressor is trying to start. It draws power, fails to get going, the overload protector trips, the system waits a few minutes, and tries again — click. That cycle repeats indefinitely.
The first component to test in this scenario is the compressor starting relay — a small part that plugs directly onto the side of the compressor and provides the electrical surge the motor needs to start. When the relay fails, the compressor cannot start even though it is mechanically sound. The symptoms are identical to a failed compressor, which is exactly why the two are so frequently confused.

How a technician properly diagnoses the relay vs. the compressor
There are three steps to a definitive diagnosis. First, pull the starting relay off the compressor and shake it — a rattle confirms the relay has failed internally (a healthy relay is completely silent). Second, test compressor winding resistance with a multimeter across all three terminals — common, start, and run. Readings within spec confirm the motor is electrically healthy. Third, if the relay has failed but the windings are good, an experienced technician can temporarily bypass the relay and manually trigger the compressor to run on its own — confirming it is mechanically sound before the new relay is even installed. When all three tests point the same way, there is no ambiguity.
Diagnosis
1
Confirmed symptoms — clicking, no cooling
Arrived and verified: refrigerator warm throughout, audible click from the back every 3–5 minutes as the compressor attempted and failed to start. Classic relay failure presentation.
2
Tested the starting relay first
Removed the starting relay from the compressor terminals and shook it — immediate rattle. Confirmed with a multimeter: open circuit across the relay terminals. The relay had definitively failed.
3
Verified the compressor itself was healthy
Measured resistance across all three compressor winding terminals — common, start, and run pins. All readings were within normal spec. The compressor motor was electrically healthy. As a final confirmation, we bypassed the starting relay and manually triggered the compressor directly — it started immediately and ran cleanly. The compressor itself was never the problem. It had simply been unable to start because the relay that initiates the start sequence had failed.
The Repair — and the Cost Difference
We had the correct starting relay in stock. Installed it, powered the refrigerator back on, and the compressor started immediately and ran quietly. Confirmed cooling was restoring within minutes. Total time on site: 30 minutes.
The contrast with the alternative is significant:
❌ Compressor replacement
Major repair
Parts + labor + waiting until Monday. And in this case, the compressor was not even the problem.
✔️ Starting relay replacement
Minor repair
A small inexpensive part. Fixed the same Saturday in 30 minutes. Hundreds of dollars less.

Why This Misdiagnosis Happens
A failed starting relay and a failed compressor produce identical symptoms — the refrigerator stops cooling and clicks repeatedly. A technician who skips the relay test and moves straight to condemning the compressor will reach the wrong conclusion. The relay is a small, inexpensive part that can be tested in under two minutes. A compressor replacement is a major repair — far more expensive and time-consuming. The correct diagnostic sequence always starts with the cheapest and simplest component.
This is not a rare mistake. Starting relay failures are one of the most common refrigerator faults across all brands — Whirlpool, Maytag, Amana, GE, Samsung — and they are routinely misidentified as compressor failures by technicians who do not work through the circuit in order. It is exactly the kind of situation where a second opinion pays for itself many times over.
⚠️ Always ask for a second opinion before agreeing to compressor replacement
Compressor replacement is one of the most expensive refrigerator repairs. Before authorizing it, ask the technician to confirm they have: (1) tested the starting relay by shaking it and with a multimeter, (2) measured all three compressor winding terminals, and (3) manually run the compressor independently to confirm it starts. If they cannot account for all three steps, get a second opinion.
Frequently Asked Questions
The most common cause is a failed compressor starting relay. The relay provides the electrical start signal the compressor motor needs. When it fails, the compressor tries to start, fails, trips the overload protector, and retries every 3–5 minutes — creating the clicking pattern. The compressor itself is usually fine. Replacing the relay resolves the issue completely and costs a fraction of a compressor replacement.
Remove the starting relay from the compressor and shake it. If it rattles, it has failed and needs replacement. A good relay is silent. A technician should also test compressor winding resistance with a multimeter across all three terminals — common, start, and run. If windings read within spec, the compressor motor is electrically healthy. The final confirmation: an experienced technician can bypass the relay and manually run the compressor directly, proving it starts and runs on its own before installing the new relay. All three steps together give a definitive, unambiguous diagnosis.
A failed relay produces the same visible symptoms as a failed compressor — no cooling, clicking attempts to start. A technician who does not test the relay before recommending compressor replacement may reach the wrong conclusion. The relay should always be tested first: it is inexpensive, simple to confirm, and fails far more frequently than the compressor itself.
Compressor starting relay replacement is significantly less expensive than a compressor replacement — the difference can be hundreds of dollars. iFixExpress waives the service call fee with any completed repair and carries common relay parts in stock for same-day service throughout Broward County.
