TROUBLE SHOOTING GUIDE

Following the procedure below to check if the oven is defective or not.

1.Check grounding before trouble shooting.

2.Be careful of the high voltage circuit.

3.Discharge the high voltage capacitor.

4.When checking the continuity of the switches, fuse or high voltage transformer, disconnect one lead wire from these parts and check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.

(TROUBLE 1) Oven does not operate at all ; any inputs can not be accepted.

Does the fan motor work when you shut the door and turn the timer?

	NO
		YES

Does the				Check continuity of interlock
Does the				Check continuity of interlock
fuse blow?				monitor switch with door shut.

	NO				NO

Replace fuse and check continuity of both interlock switch's contact and monitor switch's contact with door partially open until monitor switch contact.

Both continuity

Disconnect one side of the lead wire connected from transformer to the high voltage capacitor, and operate oven.

Continuity

NO

Normal

Replace primary, secondary interlock switch and interlock monitor switch.

Replace primary, secondary interlock switch and interlock monitor switch.

Replace high voltage capacitor.

Fuse again

Replace high voltage transformer

If outlet has proper voltage, check continuity of power supply cord.

NO Continuity

Replace power supply cord.
