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.
