Fault Codes
The main control unit (MCU) is designed with a set of pre-pro-
grammed fault codes to aid in troubleshooting. If fault codes appear
on the screen, please take note of what is displayed. Follow the next
steps:
1. Turn the MCU “OFF” by using the switch on the back of the MCU
housing. Wait 30 seconds, then turn the MCU “ON”.
2. Turn the bed on to HI HEAT for 10 minutes.
3. If no error code is present, the issue is resolved. If the same or new
error code appears, ensure that all connection are made and repeat
steps 1 and 2.
4. If the error code(s) remain, please contact customer service. You
can always access the latest technical information at www.gentherm.
