JennAir Microwave F4E4 Error Code

Before anything else, work out which kind of JennAir microwave shows F4E4, since the articles name different parts.

• Over-the-range: humidity thermistor, or wiring.
• Built-in: microwave humidity sensor, microwave appliance manager, or wiring.

A longer list for built-ins

The built-in and wall oven articles include the microwave appliance manager, and the over-the-range article does not. JennAir leaves open whether this reflects a real product difference or just wording.

Reset steps

1. Switch off the breaker for one minute.
2. Switch it on.
3. Watch the microwave for a minute for a repeat of F4E4.
4. Operate it to confirm it works.

The over-the-range page also says you may need assistance from a qualified technician.

Picking the reading that fits

The model number on the appliance settles which JennAir article covers it. Over-the-range and built-in microwaves have separate articles, and the built-in list is longer. On a call, say which applies; the appliance manager is the detail most worth repeating for a built-in.

Other humidity codes

• F3H: the general humidity code.
• F3H1: humidity sensor on over-the-range models.
• F4E2: has the appliance manager in its list too.
