Sage Microwaves Error Codes

E01

Microwave will not start; display is on but START button does nothing, sometimes accompanied by a brief relay click.

Primary Door Interlock Switch Failure

E02

Microwave stops immediately when START is pressed, or stops mid-cycle when the door is slightly touched; sometimes accompanied by a door error beep.

Secondary Door Interlock / Monitor Switch Fault

E03

Microwave display and lights work, but when START is pressed there is no heating and no usual humming sound from inside; timer counts down normally.

High Voltage Circuit Not Energizing

E04

Microwave runs (light on, fan and turntable operating, normal humming sound) but food does not heat or heats very poorly.

Magnetron or High-Voltage Rectifier Failure

E05

Microwave stops heating after a few seconds and displays an error; fan may continue briefly, then unit shuts down.

Magnetron Overheat / Thermal Cut-Out Trip

E06

Microwave display shows an internal temperature or sensor error; cooking modes that rely on humidity or temperature sensing fail or abort.

Humidity / Steam Sensor or Cavity Temperature Sensor Fault

E07

Microwave displays a fan or ventilation error; cooling fan may run continuously or fail to start, and cooking may be disabled.

Ventilation / Cooling Fan Control Fault

E08

Microwave shows a turntable or motor error; the glass tray does not rotate during cooking, or rotation is jerky and noisy.

Turntable Drive Motor or Coupler Failure

E09

Microwave beeps and displays a door or latch error even though the door appears closed; unit will not start.

Door Latch Assembly Misalignment

E10

Microwave display is blank or flickering; unit may not respond to any buttons, or resets randomly during use.

Low-Voltage Power Supply / Control PCB Fault

E11

Microwave keypad or touch panel is unresponsive or only some buttons work; display may be normal.

Membrane Keypad / Touch Control Failure

E12

Microwave interior light does not turn on when cooking or when the door is opened, but the unit otherwise operates normally.

Cavity Lamp or Lamp Circuit Failure

E13

Microwave repeatedly blows the internal fuse or trips the household circuit breaker when starting a cooking cycle.

Short Circuit in High-Voltage or Mains Circuit

E14

Microwave fan and light come on as soon as the door is closed, or the unit attempts to run with the door open.

Door Interlock Circuit Miswiring or Stuck Relay

E15

Microwave displays a sensor or weight error when using auto-cook or auto-defrost functions; manual timed cooking works normally.

Auto-Cook Sensor Calibration / Fault

E16

Microwave shows a grill or convection heater error (on combination models); grill or convection modes do not heat, but standard microwave mode may still work.

Grill / Convection Heater Circuit Failure

E17

Microwave displays a clock or RTC error; time resets frequently or cannot be set correctly.

Real-Time Clock / Control Memory Fault

E18

Microwave displays an internal communication error; some functions may be disabled or the unit may reboot intermittently.

Control PCB Communication / Interface Fault

Symptom

Microwave cavity shows rust spots or peeling paint, especially on the floor or near the door edges.

Cavity Coating Degradation

Symptom

Microwave clock and settings reset whenever the door is opened or closed.

Door-Induced Power Interruption

Symptom

Microwave display and lights work, but pressing START produces a beep and no further action; timer does not count down.

Start Circuit / Control Logic Inhibit

Symptom

Microwave does not heat evenly; some areas of food are very hot while others remain cold.

Uneven Microwave Distribution

Symptom

Microwave door is difficult to open or does not open fully when the door button or handle is used.

Door Latch Release Mechanism Binding

Symptom

Microwave door will not stay closed or pops open during cooking.

Door Latch Retention Failure

Symptom

Microwave emits a burning smell or visible smoke from the interior during or after cooking.

Cavity Contamination or Component Overheating

Symptom

Microwave emits a strong chemical or plastic smell when new or after high-temperature use.

Off-gassing of New Components or Overheated Plastic

Symptom

Microwave interior light stays on even when the door is closed and no cooking is in progress.

Stuck Door Switch or Control Relay

Symptom

Microwave is unusually noisy with rattling or vibration sounds coming from the cabinet during operation.

Cabinet Vibration or Loose Internal Components

Symptom

Microwave keypad beeps randomly or buttons appear to press themselves without user input.

Keypad Short or Moisture Ingress

Symptom

Microwave makes a crackling or popping sound and visible sparks (arcing) appear inside the cavity during cooking.

Internal Arcing in Cavity or Waveguide

Symptom

Microwave makes a grinding, scraping, or clicking noise when the turntable rotates.

Turntable Support or Motor Drive Noise

Symptom

Microwave produces a high-pitched squeal or whine from the fan area during operation.

Cooling Fan or Convection Fan Bearing Wear

Symptom

Microwave runs but makes a loud buzzing or humming noise that is much louder than normal during cooking.

Magnetron or High-Voltage Transformer Mechanical Noise

Symptom

Microwave stops mid-cycle and resets or loses power briefly, then comes back on with the clock flashing.

Intermittent Power Loss

Symptom

Microwave takes much longer than usual to heat food; water test shows slow temperature rise.

Reduced Microwave Output

Symptom

Microwave will not start at all; display is off and no lights or sounds occur when buttons are pressed.

No Power / Dead Appliance
