What Lo or Pre means

On KitchenAid freestanding and slide-in ranges including the KFEG500ESS and KSGG700ESS, the display may read Lo or Pre after you turn on the oven. This is not a malfunction. It simply shows that the oven temperature is low, below 170°F, or that the oven is still preheating. The reading changes to a temperature as the oven heats, and no action is needed.

Common causes of Lo or Pre

  • The oven is below 170°F
  • The oven is preheating
✓ One safe check you can try

1. Leave the oven door closed and give it time to heat. 2. Watch the display change to a temperature reading. 3. If it stays on Lo or Pre far longer than a normal preheat, press Cancel and try again. 4. If it still does not heat, call us. With any gas odor, leave at once and call the utility from outside.

! Why to stop there
  • A normal Lo or Pre needs no repair.
  • An oven that never leaves Lo or Pre needs its heating system tested.
  • We put the price in writing first and back repairs for 30 days.
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.

Lo or PreLo or Pre questions
Does Lo mean a problem?

No. It shows the oven temperature is low, under 170°F. It disappears once the oven heats beyond that point and a real temperature is shown, which usually takes only a few minutes.

What does Pre mean?

Preheating. The oven is still coming up to the temperature you set, and the display changes to a real temperature reading when it gets there, and then the oven is ready for food.

When should I worry?

If the oven stays on Lo or Pre for much longer than a usual preheat and food does not cook, ask us to look at it.
