KitchenAid Induction Cooktop Code FC LF: left front zone, its coil or its wiring

What FC LF means

On KitchenAid induction cooktops such as the KICU509XSS, FC LF points to the left front hotplate (cooking surface, burner or element) or the wiring that serves it. The other zones may keep working, which is a useful clue. You will see FC LF, and the left front zone stays cold or cuts out. It is a position-specific code, so it tells us which zone to start with. Owners notice one cold zone while the rest may behave normally.

Common causes of FC LF

The left front induction coil has failed
Wiring to that coil is damaged or loose
A connector at the induction module has lost contact
The module output for that zone is failing

✓ One safe check you can try

1. Turn all zones off and let the glass cool. 2. Look for cracks or marks on the left front area without touching beneath the glass. 3. Leave the breaker off for one minute, then switch it on. 4. Try another zone with the same pan; if FC LF returns, call us.

! Why to stop there

Coils and their wiring lie below the glass and are energized.
Telling a coil from the module output takes a measurement.

FC LFFC LF questions

Does FC LF mean only the left front zone is bad?

That is where the problem points. The other zones may work, but they share the same electronics, so we check the whole cooktop while we are there.

What do LF, LR, RF and RR stand for?

They are the zone positions: left front, left rear, right front and right rear. The code names the position, so tell us which zone is dead when you call.

Could my pan be the reason?

Not for FC LF. Cookware issues give different codes. If the same pan heats on another zone, that confirms the problem is with this zone.
