Why doesn't the contactor air solenoid energize when the 'Start' button is pushed on my ARCAIR Industrial Electrical?

If the contactor air solenoid doesn't energize when the 'Start' button is pushed on your ARCAIR Industrial Electrical, there might be a break in the interconnect cable between the contactor and controller; check and replace it if necessary. A defective transformer in the contactor unit could also be the cause. Finally, the contactor unit may be in a high-temperature shutdown; allow it to cool and check the fan and filter.
