Display Diagnostics; Error Codes - Amana ACE530 Service

Display Diagnostics

All repairs as described in this troubleshooting section are to be performed only after the caution procedures one
through eight listed below have been followed.
1. Check grounding before checking for possible causes.
2. Be careful of the high voltage circuit.
3. Discharge high voltage capacitor.
4. When checking the continuity of the switches or the high voltage transformer, disconnect one lead wire from
these parts and then check continuity with the AC plug removed. To do otherwise may result in a false reading
or damage to your meter.
5. Do not touch any parts of the circuitry on the P.C. Board circuit since static electric discharge may damage this
control panel. Always touch yourself to ground while working on this panel to discharge any static charge in
your body.
6. 208/230 VAC is present in the high voltage circuit board, power relay and primary circuit of low voltage
transformer.
7. When troubleshooting, be cautious of possible electrical hazard.
8. When testing convection operation, convection fan may start at any time or if oven is hot.
