Hotpoint Refrigerator: electrical arcing sound

Professional Repair Guide

What is this symptom?

If you're hearing a distinct electrical arcing sound from your Hotpoint refrigerator, especially near the compressor or electrical components, it may indicate a serious issue. This unusual noise is often associated with a faulty compressor start relay or loose wiring, which can lead to further complications if not addressed promptly. It's essential to diagnose this problem quickly to prevent potential damage.

Urgency: High

Important Tips for Hotpoint Models

Certain older Hotpoint models have been associated with electrical issues leading to safety concerns, including power surges potentially contributing to electrical faults. (Not a direct cause of arcing symptom but relevant electrical safety history.)

Possible Causes

Faulty compressor start relay / overload assembly causing electrical arcing or spark-like noise during compressor startup

How to Identify: Repeated arcing or spark-like/staccato noises at intervals when compressor tries to start, often with clicking/hum sounds prior; warm fridge/freezer due to lack of actual compressor engagement. Temperature rising could accompany it. Source near back bottom compressor area. This matches descriptions of electrical starter relay issues causing arcing-like noises. Evidence from community sources indicates electrical-related clicking may be linked to start relay issues.

Part: Compressor start relay / overload protector

Loose wiring or poor electrical connections inside the fridge's electrical system

How to Identify: Arcing or crackling noise that changes when fridge is moved slightly or vibration changes; potential intermittent power issues; visible signs of burn marks on connectors behind panels.

Part: Internal wiring harness or terminal connections

DIY Solutions

Inspect and replace start relay/overload assembly

Advanced 30-60 minutes

Tools Needed: screwdriver set, nut driver set, multimeter

Unplug the refrigerator from power.
Move the unit away from the wall and remove back panel to expose compressor and attached start device.
Visually inspect the start relay/overload assembly on the compressor side.
Perform a continuity check with a multimeter on the relay; if open circuit or rattling internal parts, replace with OEM equivalent.
Reassemble and test operation.

⚠️ Safety First: Always disconnect power before accessing electrical components.
