Oven Selector Dial Testing:
In order to test the oven selector dial on your electric range, the following steps should be taken:
- Before repairs or testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. A jolt from 220 volts can be fatal, use caution!
- In order to gain access to the oven selector dial, first move the range away from the wall and remove the back cover panel by undoing the retaining screws. This will expose the back of the oven selector dial. Note: There are many styles of ranges. If this does not describe your range, refer to your owner's manual for instructions on gaining access to your oven selector dial.
- Now you can begin to test each pair of switch contacts for continuity with your VOM. Using the ohmmeter function, set the range scale to R x 1, and touch one test lead to each terminal of the switch contacts to be tested. There will be several pairs of contacts, one pair for each setting (eg. broil, bake, etc.). Refer carefully to your wiring diagram (often placed on the inside of the access panel) when testing. It is a good idea to label the wires as you test and only remove one pair of wires at a time. If there is no continuity between any pair of contacts, the switch is defective and must be replaced.
- To install a new oven selector dial switch, remove the old switch from the control panel by undoing the nut or screws holding the switch in place, leaving all wires attached. Transfer the wires one at a time from the old switch to the correct terminal of the new switch. Check your wiring diagram to make sure all wires are on the correct terminals. Now mount the new switch to the back of the control panel and replace the cover.
REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION!!!
