Oven Cycling Relay Testing:

  1. 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!
  2. In order to gain access to the oven cycling relay, refer to your owner's manual. Removing the back panel of the range accesses most relays, but some ranges locate the relay under the oven compartment where the utility drawer is usually located.
  3. Now you can test the relay using your VOM. First, label each wire attached to the relay and remove them from the relay terminals. Using your VOM's ohmmeter function, set the range to R x 1 and touch one test lead to the terminal marked L and the other test lead to terminal H2. There should be NO continuity. Next, test the terminals marked H1 and H2. Again, there should be NO continuity. Finally, test the S and R terminals. Continuity should exist between these two terminals. If your relay does not pass all these tests, it is defective and should be replaced.
  4. To remove the relay, undo the two screws securing it to the range and replace with the correct new relay. Refer to your wiring diagram and labeled wires to ensure that the wires are on the correct terminals. Now replace the back panel or drawer and test the oven.
REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION!!!
