Whirlpool Range Lo — What It Means & How to Fix It
Also shown as Pre, LO on some models.
Lo or Pre after you start the oven is normal — it means the oven is below 170°F or still preheating, and a tone sounds when the set temperature is reached.
What this code means
Whirlpool says Lo or Pre simply shows that the oven temperature is low (below 170°F) or that it is preheating. On some models the display switches to the actual temperature at 170°F and rises in 5-degree steps. A tone sounds when the set temperature is reached.
Normal behaviour on Whirlpool ranges; whether you see Lo or Pre depends on the model.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Oven has just been turned on and is preheating | Very common | Yes — wait |
What you can try yourself
- Leave the oven to preheat with the door closed.
- Wait for the display to change and for the preheat tone.
- Put food in once the tone has sounded.
When to call a technician
- Lo or Pre is still showing after 20–30 minutes.
- The oven is not getting warm at all.
- An F code appears during preheat.
Typical professional repair cost: Nothing when preheat completes normally. If the oven is not heating, an igniter or element repair typically costs $150–$350.
