Understanding the Problem
When a Maytag MFD2561HEB refrigerator compressor fails to start the fridge will stop cooling even though the lights, fans or controls may still work. Most commonly the failure is not the compressor motor itself but the compressor start system: a start relay, overload protector (PTC or thermal fuse), or start capacitor. Those parts provide the brief extra electrical push the hermetic compressor needs to spin up. Diagnosing the start device is important because a bad relay/overload or weak/broken capacitor will make the compressor click, hum, or try to start repeatedly and then shut off, or simply stay locked and never run. Replacing the faulty start device or capacitor is usually far less expensive than replacing the compressor or entire refrigerator, but always verify with basic tests before buying parts.
Common Symptoms
Fridge warm or warming up, compressor clicking or humming but not running, unit cycling on/off rapidly, high startup noise, or a burnt electrical smell near the compressor area.
Common Causes
- Failed start relay or PTC starter (electronic starter) that no longer provides the start kick.
- Faulty thermal overload (overload protector) that opens under normal conditions or after a failed start attempt.
- Failed or weak start capacitor (on models that use a capacitor) causing insufficient starting torque.

Helpful Repair Tip
With power OFF, pull the start relay off the compressor and give it a gentle shake — a rattling sound or burned smell usually means it's bad. Also test the start capacitor with a multimeter set to capacitance or swap in a known-good capacitor of the same rating to confirm.
Frequently Asked Questions
How do I know whether the relay/overload or the compressor itself is bad?
If the compressor clicks or hums but won't start, first check the start relay/overload and capacitor. Remove the relay and overload and smell/inspect for burn marks; a rattling relay or bulging/leaking capacitor indicates failure. You can test the relay with an ohmmeter for continuity on the start and run pins and test the capacitor with a capacitance meter. If the start device checks good and the compressor still won’t run (no change when hot-wiring/start-jumping is attempted by a qualified tech) then the compressor motor may be shot and will usually require compressor replacement by a pro.
Can I replace the relay/overload or capacitor myself and how risky is it?
Many technically handy owners can replace a relay/overload or start capacitor—these parts are usually clipped to the compressor and accessible behind the rear panel. Always unplug the refrigerator first and discharge the capacitor (if present) before touching it. Use a correct-match replacement part and follow wiring orientation. If the compressor itself needs replacement or if you are uncomfortable working with mains-voltage components, call a certified appliance technician because replacing the compressor involves refrigerant recovery and specialty tools.
