What to do if the Vertiv Liebert CRV CRD100-0D00A Air Conditioner EC fan won’t start?
- Bbarbara97Jul 26, 2025
If the Vertiv Air Conditioner's EC fan won't start, begin by checking if the fan's Miniature Circuit Breaker (MCB) is closed. If it is, verify that the power voltage of each phase is normal. Also, inspect the power cable of the fan for power failure, phase loss, or low voltage. Ensure the motor isn't clogged due to high current or overheating. Check that the analog output is within the required 0-10Vdc range.
