JennAir Radiant Cooktop Code F58: Same Board Family as F42

What F58 means

F58 on JennAir electric radiant and touch-control cooktops carries the same description as F42 and F43: there may be a problem with the cooktop power control board or the associated wiring. The cooktop may not heat, may shut elements off or may display F58 as soon as it receives power. That means pans, cleaning and cool-down time are not part of the answer.

Common causes of F58

The cooktop power control board has failed
Wiring to the board is loose or damaged
Power instability affected the board
Moisture or heat damage to the board under the glass

✓ One safe check you can try

1. Turn off every element and wipe up any liquid on the glass. 2. Switch the circuit breaker off for one minute and back on. 3. Try one element on a low setting. 4. If F58 returns, leave the cooktop off. 5. Call us rather than running it again.

! Why to stop there

The board controls element power, so a failure can cause unpredictable heating.
Its wiring is behind the glass and carries line voltage.
F42, F43 and F58 share a description, so only testing tells them apart in practice.

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.

F58F58 questions

Does F58 mean the same board as F42?

They share the same wording: the power control board or its wiring. The code differs, and we test to confirm which board or wire needs attention.

Will a reset make F58 go away?

A reset only helps if the cause was a one-time glitch. If F58 returns, the board or wiring is the likely cause and should be tested.

What do you do at the visit?

We test the power board and its wiring, explain the result and quote in writing first. If you go ahead, repairs include a 30-day workmanship warranty on our labor.
