Cardale Overheating Component or Electrical Insulation Breakdown

Opener operates normally but emits a burning smell after a few cycles.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Overheating motor windings, Slipping belt or chain generating friction heat, Failing capacitor leaking, Dust buildup on PCB components

Safety first: If you smell burning, stop using the opener immediately and disconnect power.

Inspect motor and belt/chain: Look for discoloured plastic, melted belt sections, or hot spots on the motor casing.
Check for obstructions: Ensure the door moves freely to avoid overloading the motor.
Clean interior: Gently remove dust from vents and PCB with a dry brush or compressed air (power OFF).
Replace suspect parts: If the smell persists, have a technician test and replace the Cardale motor, capacitor, or PCB as needed.
