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 tranformer, disconnect one load 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.

NOTE : When electric parts are checked, be sure the power cord is not inserted the wall outlet.

Check wire harness, wiring and connection of the terminals and power cord before check the parts listed below.

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