ACP Amana High-Speed Oven Error Code B1: Touch Panel
B1 on an Amana Xpress AXP22 or MXP22 touch panel oven means the control no longer trusts the panel you press to set programs. The oven may ignore touches, react to touches you did not make, or stop partway through a menu selection. Unplug it, let it cool, dry the panel edges, and leave it off if it still acts as if someone is pressing keys.
Medium: a panel that presses itself should not be used, but unplugging the oven removes the risk.

What does ACP Amana error code B1 mean?
B1 points at the same part as B0, the touch panel, but it tends to show up as a panel that has gone wrong rather than one that is merely dull. The control compares what the panel reports with what makes sense, and when the two disagree it flags B1 and shows the code on the display. You may find the oven ignoring touches, reacting to a touch you did not make, or stopping partway through a menu selection. The maker's advice is to unplug the oven and let it sit idle while it cools, then plug it back in, and to dry the panel edges with a cloth. Liquid under the glass is a common reason for B1, because a film of liquid bridges touch zones and creates presses that nobody made. If the oven still behaves as though someone is pressing keys, switch it off at the plug and leave it off. An unattended microwave program is not safe, so do not run it that way. The panel surface, its connector, the display board input and heat damage are the other places to look.
Affected models and control systems
This applies to the Amana Xpress AXP22 and MXP22 touch panel combination ovens, as covered in the ACP Commercial Service and Training Manual. The older AXP20/MXP20 list B0 and B1 together as a touch pad code.
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
- B1 on the display
- The oven ignores touches
- The oven reacts to touches you did not make
- The program stops during a menu selection
Possible causes
Listed in ACP Amana's documentation
- Touch panel surface or its connector damaged
- Moisture or grease at the panel edge, including liquid under the glass
- Display board input from the panel failing
- Heat damage to the panel
Other likely causes — what usually sits behind error code B1 on this control. A technician confirms which one it is before any part is replaced.
- Steam from the cavity that has condensed on the inside of the glass and bridges touch zones
- A display board input that has aged so that normal presses are read as continuous
Safe checks before calling for service
- Unplug the oven and let it sit idle while it cools, then plug it back in.
- Dry the panel edges with a cloth.
- If it still behaves as though someone is pressing keys, switch the oven off at the plug and leave it off.
- Do not run a program unattended.
- Tell us what the panel did and when it started.
How a technician diagnoses error code B1
- Read the code and observe the panel for false or missed presses.
- Inspect the panel edges and the space behind the glass for moisture.
- Check the panel connector and the display board input.
- Look for heat damage along the panel.
- Replace the panel or display board only after the checks.
- Liquid under the glass cannot be dried from outside, so the panel has to be removed and checked by a technician.
- A panel that acts as if keys are pressed can run a microwave program unattended, which is not safe.
- The boards behind the panel carry high voltage and must not be opened by an operator.
How error code B1 differs from similar codes
B0 on the same oven is the missed-touch and phantom-touch entry for the same panel. B1 is reported when the control no longer trusts the panel at all.

Related ACP Amana high-speed oven error codes
Is B1 worse than B0?
Both point to the touch panel. B1 is more often tied to the panel reacting on its own, so we are more cautious about use.
Can liquid cause B1?
Yes. The maker lists it as a common reason, so keep spray cleaners away from the edges.
Should I run the oven in the meantime?
No. Leave it off at the plug until the panel is checked.
