Proline Relay Operating Without Power to Elements

Clicking noise from control area but oven does not heat

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

Burnt relay contacts, Broken PCB track to element output, Loose wiring from relay to elements, Incorrect neutral connection

Safety first: Isolate the oven from mains before opening the control panel.

Inspect PCB: Look for burnt or cracked solder joints around the heating relays and output terminals.
Check continuity: With power off, test continuity from the relay output terminal on the PCB to the element terminals. Repair any open circuit in wiring or PCB tracks.
Relay replacement: If the relay coil operates (clicks) but no continuity exists across its contacts when energized (requires safe live testing), replace the control PCB.
