Amana Microwave Error Code PCE6

PCE6 indicates a communication failure between the high voltage board, low voltage board, and/or extended memory board inside the microwave. These three boards must exchange signals to coordinate the unit's cooking functions, and when that communication breaks down the microwave shuts down and displays PCE6. The fault can be caused by loose wiring, a damaged cable, or a defective board.

No, you should not attempt to operate the microwave while PCE6 is active. The code indicates that critical control boards are not communicating properly, which means the unit cannot manage its high voltage components reliably. Continued use under this condition is unsafe and could worsen the underlying fault.

Repair costs vary depending on whether the issue is a loose connection or a failed board. A wiring fix typically involves labor costs in the range of $75 to $150. If one or more control boards need replacement, parts plus labor can bring the total to $150 to $400 or more, depending on which boards are involved. For older units, it is worth comparing repair costs against the cost of a replacement microwave before proceeding.

Unplugging the microwave for one full minute and then reconnecting it is the first recommended step, and it can clear PCE6 if the fault was caused by a temporary power glitch. If the code returns after the reset, there is a persistent wiring or board issue that requires hands-on diagnosis. A reset alone will not fix a failed component or a loose connector.

Start by unplugging the microwave for one minute, then plug it back in and test. If the code persists, the internal wiring connections between the H.V. board and L.V. board need to be inspected, along with the cable between the L.V. board and extended memory board. Because this repair involves accessing the high voltage section of the microwave, which retains lethal charge even when unplugged, it should be performed by a qualified appliance technician.
