Eb6 Blower shut down for voltage or power module temperature

What the control is telling you

The motor shut down because of over or under voltage, or because its power module overheated.

Applies to: ComfortBridge communicating air handlers AVPTC**14 (B* revision board) and MBVC1201/1601/2001 modular blowers

Likely causes

• Line voltage to the air handler too high or too low
• High ambient temperature

Test and repair steps

1. Check power to the air handler and confirm line voltage is within the rating plate range.
2. Check for high temperature around the unit / poor ventilation.
3. If voltage and temperature are fine and the code repeats, check the motor and control.
