Common Issues with Goldstar ER654M Microwave and Troubleshooting Tips
Many problems with microwave ovens are straightforward to diagnose and fix. Below are some typical issues and their solutions.
1. Microwave Not Powering On
Possible Causes:
- Power supply issues
- Blown fuse
- Faulty door switch
- Internal circuit failure
Troubleshooting Steps:
- Verify that the microwave is plugged securely into an operational outlet.
- Test the outlet with another device to ensure it's working.
- Check the circuit breaker or fuse box for tripped breakers or blown fuses, and reset or replace as necessary.
- Unplug the microwave and inspect the fuse located inside the unit (refer to the user manual for fuse location). Replace it if blown.

2. Microwave Not Heating
Possible Causes:
- Magnetron failure
- High-voltage diode or capacitor failure
- Faulty door switch
- Control board malfunction
Troubleshooting Steps:
- Test if the microwave’s turntable rotates—if it doesn't, it might indicate motor or drive issues but doesn't necessarily mean no heating.
- Place a microwave-safe cup with water inside and run the microwave for 30 seconds. If the water warms up, the microwave is working; if not, further checks are needed.
- Unplug the microwave and access the internal components (refer to the manual). Use a multimeter to test the magnetron, diode, and capacitor for continuity and proper resistance values.
- If the magnetron is faulty (no continuity), it needs replacement. These parts are usually replaced by professionals.
- Check the door switches for continuity when the door is closed—faulty switches can prevent heating as a safety measure.
Note: Due to high-voltage components involved, it's recommended to seek professional repair for heating issues.
