Display Diagnostics; Error Codes - Amana ASE7000 Service Manual

Display Diagnostics

To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires it.
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.

Error Codes

During operation, the display may show the following service codes:
NOTE: Before scheduling service for any error codes, instruct customer to unplug oven for 1 minute,
reconnect power, and retest. If unit operates properly, no service call is required.
