Baxter Bakery Oven Error Code E11: Slow Heating

What does Baxter error code E11 mean?

The OV520 compares how quickly the chamber temperature rises against what it expects. When the rise is too slow, the Smart Touch screen turns yellow and shows E11, Heating Error. The manual's explanation is only that the oven is heating slow. It says the cycle can continue and that the time may need extending, and that if the problem continues you should contact a Baxter service technician. There is no mention of a burner here, so this entry covers both electric and gas ovens in the OV520 family. The manual lists no causes, so anything about why heating is slow is our likely reasoning. A heavy load, an open door or a worn heat source could all be behind it. The display reads Yellow screen: Heating Error with E11.

Affected models and control systems

This code is listed for the Baxter OV520G1 and OV520G2 (gas) and OV520E1 and OV520E2 (electric) rotating rack ovens with Smart Touch control, in Operator Manual form 36764 Rev. D.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• Yellow screen with Heating Error and E11
• Chamber temperature climbing slower than usual
• Bake time needing to be extended

Possible causes

Likely causes — what usually sits behind error code E11 on this control. A technician confirms which one it is before any part is replaced.

• Heavy load of cold product or an overfull rack pulling the temperature down
• Door left open or not sealing, letting heat escape
• Heat source weaker than it should be, for example a worn element or low gas pressure
• Temperature sensor reading lower than the real chamber temperature

Safe checks before calling for service

How a technician diagnoses error code E11

1. Read the screen history and see how often E11 occurs.
2. Time a heat-up from cold and compare it with the oven's normal.
3. Check the heat source: elements and contactors on electric ovens, burner and gas pressure on gas ovens.
4. Check the temperature sensor against a reference thermometer.
5. Check the door seal and air leaks.
6. Repair the weak part and time another heat-up.
