What Err means on a Maytag microwave

The Err code on a Maytag microwave is triggered when the cook time entered by the user exceeds the maximum allowed duration for the selected cooking mode. This is a built-in input validation limit, not a hardware fault or sensor failure. The control board compares the entered time against preset thresholds for each mode and rejects settings that fall outside the allowed range before cooking begins.

The time limits are specific to each cooking function. Bake, Broil, and Top Brown modes have a maximum setting of 45 minutes. Warm and Speed Cook modes allow a longer maximum of 60 minutes. If a time entry exceeds either of these thresholds, the control board displays Err immediately and does not initiate the cycle. The microwave is functioning correctly when this code appears, as it is enforcing designed operational parameters.

This error is almost always caused by accidental key entry, such as pressing an extra digit or entering time in an incorrect format. For example, entering 90 minutes when the mode only allows 45 minutes will immediately trigger the error. No components are damaged or malfunctioning when this code appears. Clearing the entry, re-entering a time within the allowed limit, and restarting the cycle will resolve the issue in virtually all cases.

Common causes of Err

  1. 01

    Cook time entered exceeds the mode maximum

    Wiring / connection

    The most common cause is simply entering a time longer than the mode allows. Bake, Broil, and Top Brown cap at 45 minutes, while Warm and Speed Cook cap at 60 minutes. Check your entry and reduce the time to fall within the allowed range.

  2. 02

    Accidental extra digit entered on keypad

    Wiring / connection

    Pressing an unintended digit can push the time entry well above the maximum, such as entering 450 minutes instead of 45 minutes. Review the display carefully before confirming the time setting.

  3. 03

    Incorrect cooking mode selected for the intended task

    Wiring / connection

    A user may select Bake or Broil when intending to use Warm, giving the impression the time limit is too restrictive. Switching to the correct mode, such as Warm for long low-heat holds, provides a higher time ceiling of 60 minutes.

  4. 04

    Sticky or repeating keypad button

    Part replacement

    A keypad button that registers multiple presses can multiply the entered digits, causing the time to exceed the allowed maximum without the user intending it. If the error occurs repeatedly with normal single key presses, inspect the keypad membrane for sticking or damage.

Frequently asked questions about Err

What does Err mean on a Maytag microwave?
The Err code on a Maytag microwave means the cook time you entered is longer than the maximum allowed for the selected cooking mode. Bake, Broil, and Top Brown modes allow a maximum of 45 minutes, while Warm and Speed Cook modes allow up to 60 minutes. This is not a malfunction but a built-in input limit enforced by the control board. Clearing the entry and re-entering a time within the allowed range will resolve the error.
How do I fix the Err code on my Maytag microwave?
Press the Cancel or Clear button to clear the current entry and dismiss the error. Select your desired cooking mode again and enter a time that falls within the allowed maximum for that mode. For Bake, Broil, or Top Brown, enter 45 minutes or less. For Warm or Speed Cook, enter 60 minutes or less. The microwave will accept the entry and start normally once the time is within range.
Is the Err code on a Maytag microwave a safety concern?
No, the Err code is not a safety issue. It is a protective input limit that prevents the microwave from being set to run for an excessively long uninterrupted period in certain modes. The appliance is working as designed when it displays this code. No components are at risk, and the microwave has not been damaged.
Will resetting the microwave clear the Err code?
Yes, pressing the Cancel or Clear button will clear the Err code immediately. You can also unplug the microwave for 30 seconds and plug it back in to reset the control board. However, if you re-enter the same time that exceeded the limit, the error will return. The fix requires entering a compliant cook time, not just resetting the unit.
How much will it cost to repair a Maytag microwave showing the Err code?
In the vast majority of cases, there is no repair cost at all, since the Err code is caused by an incorrect time entry rather than a faulty component. If a sticking or malfunctioning keypad is causing the code to appear repeatedly despite correct input, replacing the keypad membrane typically costs between 20 and 80 dollars for the part, with additional labor costs if a technician is needed.
