00520014 OEM 120 Minute Mechanical Timer suits Ovens and Cookers, Two Outer Terminal Connection, Replacement Cooking Timer

Part 00520014 is an OEM 120-minute mechanical timer. It's an aftermarket part made to the original equipment pattern rather than a factory part from the appliance brand. Only the two outer terminals are used to wire it in. This timer doesn't suit every appliance that runs a 120-minute dial, so put your old one beside the photos and compare the body, shaft and terminal layout before you order.

Signs a 120 minute mechanical timer has failed

Turning the knob winds a spring-driven mechanism that counts back down to zero over the set time, up to 120 minutes. At the end of the count, the internal contacts change over to cut the circuit or end the cycle. Wear on the clockwork or burnt contacts cause most failures. The dial might stop partway and never reach zero, spin freely without ticking, or refuse to hold a setting. Burnt contacts can leave the appliance dead whatever you set, or stop it switching off when the time runs out.

Part details

• OEM part number 00520014
• Mechanical timer with a 120 minute range
• Wired using the two outer terminals only
• Suits selected models only, compare with your old timer

Swapping the timer

Switch off at the wall, or isolate the circuit at the switchboard if the appliance is hard-wired, and leave hard-wired work to a licensed electrician. Pull the knob and remove the panel to reach the timer. Photograph the wiring before you disconnect it, then connect the leads to the two outer terminals on the new timer. Test it on a short setting and check it counts down and switches off.

Questions about this part

How do I know this timer will suit my appliance?

Check the old timer first. It should have a 120 minute dial and use two outer terminals for its wiring. Then compare the body size, shaft shape and mounting points with the photos. If any of those differ, this timer is not the right match.
