Symptom
Condensation or water droplets form on the control panel or door glass during and after cooking.
Excess Condensation / Venting Issue
Symptom
Control panel buttons respond slowly or sometimes not at all, especially after long cooking sessions.
Heat-Related Control Panel Malfunction
Symptom
Oven display and controls are completely dead; no lights or response when power is applied.
No Power / Dead Appliance
Symptom
Oven does not heat at all on any setting, but the display and light work normally.
Complete Heating Failure
Symptom
Oven door glass is very hot to touch during normal baking, hotter than usual.
Insufficient Door Insulation / Cooling
Symptom
Oven door will not close fully; heat escapes and cooking is inefficient.
Door Misalignment / Hinge Wear
Symptom
Oven door will not open after a self-clean or high-temperature cycle.
Door Lock Stuck Closed
Symptom
Oven emits a high-pitched buzzing or humming noise from the control panel area.
Electrical Noise from Transformer or Relay
Symptom
Oven heats but cooks very unevenly; back of the oven is much hotter than the front.
Uneven Heating / Poor Air Circulation
Symptom
Oven heats but does not reach the set temperature, food takes much longer to cook than expected.
Underheating / Temperature Inaccuracy
Symptom
Oven knobs are very stiff or difficult to turn, or selector knob does not click into positions.
Mechanical Selector Switch Wear
Symptom
Oven light does not work, but all other functions are normal.
Oven Lamp Failure
Symptom
Oven makes loud banging or rattling noises when the convection fan is running.
Mechanical Noise from Fan Assembly
Symptom
Oven overheats, burning food even when set to a low temperature.
Overheating / Temperature Runaway
Symptom
Oven produces a strong burning smell or smoke when heating, even when empty.
Contamination / Insulation or Component Overheating
Symptom
Oven trips the circuit breaker or RCD as soon as it is turned on or when heating starts.
Electrical Short or Earth Leakage
Symptom
Timer or clock works, but oven will not start unless the timer is set in a specific way.
