AccuPop Fail Minor Easy DIY

Whirlpool Microwave AccuPop Fail — Popcorn Sensor Fault

Whirlpool Microwave · Error code AccuPop Fail

What AccuPop Fail Means

The AccuPop popcorn sensor could not detect the popping pattern correctly. The unit aborts the AccuPop / Popcorn cycle but manual cook still works.

Symptoms

  • 'AccuPop Fail' on the display
  • Popcorn cycle aborts early or burns
  • Manual time-cook still works

Common Causes

1
Wrong popcorn bag size for the cycle

AccuPop expects a standard bag — mini bags or jumbo bags can throw it off.

2
Dirty / greasy AccuPop sensor

The sensor sits in the steam path and fouls over time.

3
Failed AccuPop sensor

Same family as the humidity sensor; replace if cleaning doesn't help.

How to Fix It

  1. Power down at the breaker for 1 minute.
  2. Use a standard 3.0–3.5 oz microwave popcorn bag and place it flat in the center of the turntable.
  3. Clean the cavity (especially the top vent area) and let it cool fully before retrying.
  4. If AccuPop Fail returns on multiple cycles, replace the AccuPop / humidity sensor per the model's tech sheet.
  5. Use manual time-cook for popcorn until the sensor is replaced.
