Maytag Electric Cooktop Code F40: Touchpad or Power Control Board

Medium · inspection needed

Code: F40
Appliance: Cooktop
Brand: Maytag
Warranty: 30-day workmanship

What F40 means

F40 on a Maytag electric or induction cooktop points to the user interface (the touchpad), the cooktop power control board, or the wiring between them. The control cannot get a normal reading from one of these parts, so the cooktop may not heat or may ignore the keys. The brand gives one instruction: switch off the breaker for one minute, switch it on, and monitor the cooktop for one minute to confirm the code does not return.

Common causes of F40

Touchpad (user interface)
Cooktop power control board
Wiring between the touchpad and the board
Supply to the control

✓ One safe check you can try

1. Turn the cooktop's breaker(s) off and wait one minute. 2. Turn them on. 3. Wait a minute, then confirm the cooktop works with a pan. 4. If F40 returns, do not repeat the reset; leave the cooktop off and call us.

! Why to stop there

Three possible areas share this one code, so a test is needed to pick the right one
We check connections first, since a touchpad and a board cost very differently
You approve a written price before any part is ordered

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F40F40 questions

Is it the touchpad or the power board?

The code covers both of them and the wiring in between. We test each one separately and check the connections first, so you only pay for the part that has actually failed.

Will a reset fix it?

Sometimes a one-time communication glitch clears. If F40 returns, the reset has done what it can and the circuit needs testing, so leave the cooktop off until we have checked it.

How long does a repair take?

That depends on the part involved. We test first, tell you plainly what we find, and give a written price before we begin, so you know the cost of the repair before any work starts.
