ACP Amana ACE14 / MCE14 Oven Error 5: Panel Short or Wrong Board
Error 5 on an Amana ACE14 or MCE14 touch pad speed-cook oven means the touch panel is shorted or an incorrect high-voltage board was installed. The oven does not start programs. Unplug it, wipe up liquid around the panel, wait one minute, reconnect, and stop using it if Error 5 stays.
Medium: the oven will not start programs, but it is safe to leave unplugged.

What does ACP Amana error 5 mean?
Error 5 has two quite different explanations, and the control cannot tell which applies. The first is a shorted touch panel. A spill or grease film that reaches the panel can bridge its contacts, and the control reads that as a short. The second is a wrong high-voltage board, which turns up after a repair when a part from another model was fitted, so the control sees a board that does not match the oven. In both cases the oven does not start programs. The maker advises a restart first: unplug the oven, wipe up any liquid around the touch panel, and leave it unplugged for one minute. Reconnect power and test it. That is enough if the cause was moisture that has now dried or been wiped away. If Error 5 stays, stop using the oven. The manual's list covers the touch panel for moisture or damage, the high-voltage board model, a recent repair or board swap, and the wiring between the panel and the boards. A shorted panel or a board from another model needs a technician, and the boards behind the panel carry high voltage.
Affected models and control systems
This applies to the Amana ACE14 and MCE14 touch pad speed-cook ovens, as covered in the ACP Commercial Service and Training Manual. The ovens' other numbered errors cover separate parts.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Error 5 on the display
- The oven will not start programs
- The error follows a spill or cleaning
- The error follows a repair or board replacement
Possible causes
Listed in ACP Amana's documentation
- Touch panel shorted by moisture or damage
- Wrong high-voltage board model installed
- Recent repair or board swap with a part from another model
- Wiring between the panel and the boards damaged
Other likely causes — what usually sits behind error 5 on this control. A technician confirms which one it is before any part is replaced.
- A board that was swapped during an earlier repair and does not match the ACE14 or MCE14 model
- Grease and cleaner that wicked under the panel overlay and sits across two contacts
Safe checks before calling for service
- Unplug the oven, wipe up any liquid around the touch panel and leave it unplugged for one minute.
- Reconnect power and test it.
- If Error 5 stays, stop using it.
- Tell us about any recent repair or board swap.
- Do not open the oven; the boards behind the panel carry high voltage.
How a technician diagnoses error 5
- Read the error and ask about spills and recent repairs.
- Inspect the panel for moisture, damage and shorted traces.
- Confirm the part number of the installed high-voltage board matches the model.
- Check the wiring between the panel and the boards.
- Replace the panel or the board with the correct part.
- A part number can only be confirmed against the model's parts list, and a wrong board cannot be spotted by eye.
- Moisture under the panel overlay cannot be dried from outside.
- The boards behind the panel carry high voltage and must not be opened by an operator.

Is Error 5 a spill or a bad board?
It can be either. A shorted panel often follows a spill, and a wrong board follows a repair with the wrong part.
Will it clear if the panel dries?
It can. Wipe the area and leave the oven unplugged for a minute first.
Why does a repair history matter?
A board from another model produces this error, so we need to know what was replaced.
