ELECTRIC COMBI OVENS - SERVICE PROCEDURES AND ADJUSTMENTS
HEATING ELEMENTS
WARNING: THE FOLLOWING STEPS REQUIRE POWER TO BE APPLIED TO THE UNIT DURING THE TEST. USE EXTREME CAUTION AT ALL TIMES.
1.Measure the voltage at the heating element terminals and verify it against the data plate voltage.
A.If voltage is incorrect, find the source of the problem.
2.If voltage is correct, check current draw (amps) through the heating element lead wires. If current draw is correct then heating element is ok. See table below for proper values.
A.If current draw is not correct then, replace heating element.
3.Check for proper operation.

OVEN DOOR ADJUSTMENT
NOTE: Follow the steps in the order outlined below for proper door adjustment.
1.Turn the oven off.
2.Check the level of the oven from left to right and front to back, in the exact location where the oven is to be positioned.
A.If the oven is not level, make the necessary adjustments before proceeding to the next step.
B.If the oven is level, then proceed to step 3.
3.Loosen the hinge screws just enough to adjust the door position but so the door stays when not being moved or supported.
4.Position the door square with the oven as shown below.
5.Tighten the hinge screws after adjusting.
WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.
6.Remove the right side panel and the control panel as outlined under ”COVERS AND PANELS”.
7.Loosen the screws on the door roller (striker) just enough to adjust its position but stays when not being moved.
