What E23 Means
Whirlpool documents E23 as the oven not reaching pre-heat temperature within thirty minutes, with a possible problem in the heater, the appliance control board, or the associated wiring. It is a heating-performance code on convection-equipped models.
Common Causes of E23
- Failed or weak heating element
- Blocked vents or heavily loaded grease filters
- Control board fault
- Thermal sensor reading low
🔧 One Safe Check You Can Try
Isolate the appliance for five minutes and restore power. Check the cavity is empty of anything blocking airflow and that the vents are not obstructed by grease build-up - on an over-the-range unit the filters and vents load up quickly. Clean or replace the grease filters. If pre-heat still fails, the heating element or control needs a technician. A microwave capacitor can hold a lethal charge long after the oven is unplugged - this is the one appliance where "unplug it and have a look" is genuinely dangerous advice.

- Element and control work means opening an overhead-mounted cabinet.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
