If the turntable turns but the microwave doesn't heat, check for relay failure. If that's not the issue, check for noise filter failure. If the problem persists, check for power supply or magnetron failure.
Why is the display not illuminated on my TIA Microwave Oven?
If the display numbers are not illuminated, it could be due to several reasons: * No or low input voltage: Measure the input voltage; it should be 28 Volts DC. Check the load shed circuit on the aircraft. * Check the load shed circuit on the aircraft and load shed fuse in the microwave. * Check the load shed fuse in the microwave (P/N 400-1860-01 only) and noise filter. * Noise filter failure: Check the controller card for failure. * Controller card failure: Check the liner overheat thermostat. * Check the liner overheat thermostat.
