Understanding the Problem
When a refrigerator compressor struggles to start the cooling cycle it often points to a failed start device: the start relay, overload protector, or (less commonly) a start capacitor. On a Maytag MFD2561HEB these parts work together to give the compressor the extra torque it needs to begin running. If one of them fails the compressor may hum, click, run intermittently, or not run at all — frequently causing the fridge to warm up. Failure of these parts is common with aging units, power interruptions, or when the compressor draws excessive current. The relay and overload are relatively inexpensive and replaceable without swapping the entire compressor. Correct diagnosis is important because a failed start device can mimic a locked/stuck compressor — replacing the relay/overload can often restore operation, but a seized compressor will require a compressor replacement or professional repair.
Common Symptoms
Compressor hums but won’t start, repeated clicking at the rear, fridge warm or cooling intermittently, freezer icing while compressor won’t sustain run, tripped household breaker.
Common Causes
- Failed start relay (internal contacts or PTC device degraded)
- Blown or open overload protector (thermal cutout not allowing start current)
- Faulty or missing start capacitor (if equipped) or weak capacitor reducing starting torque

Helpful Repair Tip
Before ordering parts, disconnect power and listen at the rear: a repeated click or a humming compressor that doesn’t start usually indicates a bad start relay/overload. Remove the relay from the compressor and test for continuity or try a known-good relay kit for a quick confirmation.
Frequently Asked Questions
How can I test the start relay and overload on my MFD2561HEB?
Always disconnect power first. Remove the relay/cover from the compressor terminals. Do a visual and shake test: a loose rattle or burned smell suggests failure. Test with a multimeter for continuity of the relay terminals (follow the relay wiring diagram) and for an open overload. You can also try a known-good relay/start kit temporarily (or a hard-start kit where appropriate) to see if the compressor starts. If you’re not comfortable working near the compressor or testing live circuits, hire a technician.
Can I replace the start relay/overload myself and how much will it cost?
Yes — if you are comfortable unplugging the fridge, accessing the rear compressor area, and swapping the small relay/overload parts, it’s a straightforward DIY job. Parts typically cost from $15–$60 depending on OEM vs universal kits. If the compressor itself is bad, costs are much higher and typically require a professional for compressor replacement or sealed system work. Always verify the correct part by checking the fridge’s service tag or tech sheet before ordering.
