Magic Chef freezer shows E5 and may not cool properly; compressor may not start or may short-cycle.

Safety warning: Unplug the freezer before accessing the compressor area. The compressor and nearby tubing can be very hot. Do not puncture or cut any sealed system lines.

Steps to check:

• Access the compressor compartment: Remove the rear lower access panel to expose the compressor, start relay, and overload protector.
• Listen for clicking: Plug the unit in briefly and listen. Repeated clicking every few seconds with no sustained compressor run often indicates a bad start relay or overload. Unplug again before proceeding.
• Remove the start relay and overload: Gently pull the plastic cover off the compressor terminals. Disconnect the PTC relay and overload protector.
• Shake test the relay: Lightly shake the PTC relay. If it rattles like broken pieces inside, it is likely bad.
• Measure relay resistance: Using a multimeter, check resistance across the relay terminals. An open circuit or burned smell indicates failure.
• Inspect the overload: Check for burn marks or a melted housing. Test continuity; an open overload at room temperature is defective.
• Replace faulty components: Install a new Magic Chef-compatible PTC start relay and overload protector, matching the original wiring orientation and terminal positions.
• Test compressor operation: Reinstall the cover, restore power, and observe. The compressor should start smoothly and run without repeated clicking. Monitor for cooling over several hours.

Important: If the new relay and overload still trip or the compressor draws excessive current and overheats, the compressor itself may be failing. This requires sealed system service by an EPA-certified technician.
