Why Does My Midea MAD50C1AWS Keep Showing P2?
Exact model: Midea MAD50C1AWS
Choose the situation that matches what your machine actually does. Follow that repair route and check its result before trying another.
Safety: Disconnect the relevant power source and isolate moving, hot or pressurized components before service.
Bucket genuinely full or not fully seated
When this applies: The P2 indicator appears with a full bucket or a bucket that is not completely installed.
What this suggests: On pump-free MAD50C1AWS, Midea defines P2 as bucket full OR incorrectly positioned, not as a failed condensate pump.
What to check
- Power off, slide the bucket out level and empty it.
- Inspect the runners and any fitted bucket float for debris, sticking or damage.
How to correct it
- Clean and refit the bucket without forcing it. Replace a cracked or deformed bucket only with a revision-matched assembly; the catalog lists 12120100A16385.
Check the result: P2 clears with an empty seated bucket; later, a genuinely full bucket must again stop operation.
P2 persists with an empty, properly seated bucket
When this applies: The bucket and seating have been checked, but the full/missing bucket input remains active.
What this suggests: A switch that does not change contact state between actuated and released positions may be damaged, but the terminal assignment must be established from its real markings.
What to check
- Observe whether the intact bucket reaches its original switch actuator. Do not tape down or bridge the protection mechanism.
- For trained service with the unit safely isolated, identify the bucket microswitch at OEM diagram position 17.2: Midea part 17400512000009.
How to correct it
- A qualified technician may replace the confirmed failed microswitch with the same correctly matched part, securing its original mechanical position.
- If P2 persists with a working switch, investigate the harness/control input; no verified MAD50C1AWS-specific cabinet disassembly or terminal map was found.
Check the result: Test BOTH conditions after repair: installed empty bucket permits running and a truly full bucket still triggers P2.
Confirm the repair
P2 clears and the unit stops appropriately when the bucket is deliberately removed or becomes full.
