Maytag Oven CAL Error Code — What It Means
CAL is not an error code on Maytag ovens. It indicates the oven calibration feature is active, which allows you to adjust the baking temperature offset from the factory setting. If you see CAL on the display, the control is either in calibration mode or showing the current temperature offset. This is a normal function used to compensate when the oven runs consistently hotter or cooler than the set temperature. Maytag calibration adjustments typically range from +30°F to -30°F in increments of 5°F or 10°F, depending on your control style.
Common Causes
- Calibration mode was entered Someone accessed the calibration menu by holding a button combination or selecting a settings option, so the display now shows CAL or a calibration offset value.
- Oven temperature runs consistently off The oven bakes hotter or cooler than the set point, and the control needs a temperature offset adjustment to compensate.
- Control display is stuck or frozen A temporary control glitch is holding the calibration screen active, and a power reset may clear the display.
- Temperature sensor is malfunctioning If calibration does not fix inaccurate baking, the oven temperature sensor may be reading incorrectly and needs testing or replacement.
- Ignitor is dirty or weak (gas models) A worn or dirty ignitor can cause poor combustion and uneven oven temperatures that calibration alone cannot correct.
Step-by-Step Fix
- {‘lead’: ‘Check the display carefully’, ‘text’: ‘to confirm you are seeing CAL, 0°F CAL, or a similar calibration message, not a true fault code with letters like F or E.’}
- {‘lead’: ‘Exit calibration mode’, ‘text’: ‘by pressing Cancel or Stop, or by turning the oven off, then check if the display returns to normal standby.’}
- {‘lead’: ‘Perform a power reset’, ‘text’: ‘by switching off the oven circuit breaker or pulling the fuse for one full minute, then restore power and recheck the display.’}
- {‘lead’: ‘Test actual oven temperature’, ‘text’: ‘with a reliable oven thermometer at 350°F for 20 minutes to measure how far off the oven bakes from the set point.’}
- {‘lead’: “Enter calibration mode using your model’s method”, ‘text’: ‘(Settings/Options, Temp down-arrow hold, or Bake hold) and adjust the offset in 5°F or 10°F increments to match your thermometer reading, then press Start to save.’}
- {‘lead’: ‘Inspect the oven temperature sensor’, ‘text’: “if calibration does not solve the problem, checking for visible damage, secure connection, or abnormal resistance values per your model’s specifications.”}
- {‘lead’: ‘Examine the ignitor (gas ovens)’, ‘text’: ‘or heating elements (electric ovens) for wear, carbon buildup, or weak glow, and replace if they do not reach proper operating condition.’}
Parts Often Needed
| Part | Notes |
|---|---|
| Oven Temperature Sensor (RTD) | Amazon | Replace if the sensor is damaged or reads out of spec and calibration does not correct temperature accuracy. |
| Oven Ignitor (Gas Models) | Amazon | Replace if the ignitor glows weakly, is carbon-fouled, or does not open the gas valve reliably. |
| Electronic Oven Control Board | Amazon | Replace only if the calibration feature is unresponsive, the display is permanently stuck, or temperature regulation fails after sensor and ignitor checks. |
When to Call a Pro
Call a professional if you are uncomfortable entering calibration mode through your control’s menu system, if the CAL display persists after a full power reset and manual exit, or if oven temperature remains inaccurate after you complete calibration and verify the sensor and ignitor are functioning. A technician can test sensor resistance, ignitor draw, and control board outputs with proper meters and interpret your model’s calibration limits and component specifications accurately.
