Baxter Bakery Oven Error Code E5: Heat Disabled, High Limit Tripped
E5 on a Baxter OV520 yellow Heating Error screen means the manual-reset high temperature limit has tripped and heat is shut off. The bake cycle can continue but without heat, so time may need extending, and the manual says to contact a Baxter service technician.
High: heat is disabled by a safety limit, so the oven cannot bake until it is checked and reset.

What does Baxter error code E5 mean?
The OV520 has a high temperature limit, a safety device that cuts heat if the oven chamber gets too hot. This one is manual reset, which means it stays tripped until someone resets it, and the control cannot restart heating by itself. When it trips, the Smart Touch screen turns yellow and shows E5, Heating Error, because heat is disabled. The manual says the bake or cook cycle can continue but the oven will not heat, so product may need more time or may not cook at all. It lists no causes for the trip. The action is to contact a Baxter service technician. A yellow screen in the manual's table is the middle severity, below the red screens for dangerous conditions. The display reads Yellow screen: Heating Error with E5.
Affected models and control systems

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 E5
- Oven chamber not heating or cooling down
- Bake times running long or product underbaked
Possible causes
Likely causes — what usually sits behind error code E5 on this control. A technician confirms which one it is before any part is replaced.
- Chamber overheated earlier, for example from a blocked vent or a stuck control, which tripped the limit
- A failed temperature sensor or control relay allowed overshoot
- Limit device itself weak and tripping below its normal setting
Safe checks before calling for service
- Note that heat is disabled and do not rely on this oven to cook product until it is checked.
- Switch the oven off and let the chamber cool.
- Check outside the oven that the exhaust and room ventilation are not blocked.
- Do not open panels to look for a reset button; that is for a technician.
- Note the time, what was baking, and whether the oven was running hot just before E5, for the service call.
How a technician diagnoses error code E5
- Read the screen history to see whether E5 follows other heating codes.
- Find why the limit tripped, checking for overshoot from the temperature sensor or the heat control.
- Check chamber airflow and the convection fan and exhaust path.
- Test the limit device continuity after it has been reset.
- Reset the limit only after the cause is found and run a heat-up while watching the temperature.
- The high limit is a safety device, and resetting it without finding the cause is unsafe.
- It sits inside the oven at live voltage and gas controls.
- Finding the cause needs a meter, a reference thermometer, and the oven's wiring information.
