Code Error Solution

E003

User interface overheating
To address this issue, ensure that the upper oven door is fully closed. Replace the upper door hinges if they are defective. Then, check the connections of the upper cooling fan wire harness and reattach any loose wires or replace them if damaged. If that doesn’t resolve your problem, call a specialist.
To do this, you need to contact us (866) 905-3275 Or fill out the form and we will contact you as soon as possible book online

E005 / E009

Communication error
Disconnect the oven’s power supply. Inspect the wire harness connections between the electronic oven control board and the user interface. If there are any broken wire harnesses, reconnect or replace them. If the wire connections are intact, the user interface may need to be replaced.

E010

User interface memory error
Disconnect the power supply, examine the wiring harness connections between the control board and the interface, and replace any damaged wires. If the issue occurs again, call a specialist.

E011

Faulty user interface or stuck button
Press the stuck button to release it. If the problem reoccurs, consider replacing the user interface.

This is my second call to AAR and I’ve had 3 appliances repaired so far. They are very responsive, efficient, and straightforward. I had had clear explanations of the service and clear billing. No surprises and perfectly working appliances! They also leave their work areas CLEANER than they find them. Great service!

I want to take the chance to say thank you. Not having a functioning dryer was difficult and frustrating. However, I need to give credit where credit is due. Ahmad went the extra mile to help my wife and I; not only by doing repair work, but also by patiently assisting us with tips when it seemed like problems were stubborn and weren’t not being solved. He made himself available and we could reach out when in doubt. We were blessed to have an effective repairman.
