Both refrigerator and freezer are warm; compressor not running; no error code.

High-voltage safety: Unplug the refrigerator and wait several minutes before touching compressor components. Compressor diagnosis beyond basic checks should be done by a professional.

Steps:

• 1. Listen for compressor: After plugging in, listen at the back. If you hear repeated clicking every few minutes but no steady hum, the start device may be failing.
• 2. Access compressor: Remove the rear lower cover to expose the compressor and start device (relay/PTC and overload) on the compressor terminals.
• 3. Inspect start device: Remove the start relay/overload assembly and shake it gently. If it rattles or shows burn marks, replace it with the correct Haier part.
• 4. Test overload: With a multimeter, check continuity through the overload protector. Replace if open.
• 5. Compressor winding test (advanced): Measure resistance between compressor terminals. Very high or zero readings may indicate a bad compressor, which requires professional replacement.
• 6. Control board: If the compressor and start components test good but never receive power, the main control board may be faulty and require replacement.
