Possible Causes
Loose terminal in fused spur, worn wall switch contacts, loose push-on connectors at Rangemaster motor, failing air switch module
How to Fix / Troubleshooting
Safety first: Isolate power at the breaker before inspecting any electrical components.
- Check wall switch and spur: Remove the faceplate and fused spur cover. Tighten all terminal screws and inspect for heat discolouration. Replace any damaged components.
- Inspect appliance connections: At the disposal junction box or terminal cover, ensure all push-on connectors and screw terminals are secure.
- Test air switch: For air-switch models, temporarily bypass the air switch (qualified persons only) to see if the problem disappears. If so, replace the air switch module.
- Monitor: After tightening and/or replacing suspect components, test over several days. Persistent intermittent faults may require a professional electrician to perform further diagnostics.
