Fan speed control is not working Inspection

What does Fan speed control is not working entail

A top-rated mobile mechanic will come to your home or office to determine the source and cause of the fan speed control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

How it's done

  • The mechanic will perform a thorough inspection of the HVAC system. The mechanic will check for motor operation by removing the connector and checking the condition of both male and female sides. They will probably test motor operation by connecting a battery via alligator clips to the motor’s plug pins and see if it runs direct from that source. If the motor works fine, the next step is checking the resistor. The mechanic will unplug the resistor from its connector and check for burnt terminals. That often signifies a bad resistor. To check resistor functionality, the mechanic will use a multimeter set to the resistance function, then measure the resistances from a common point on the connector to the various pins to make sure the required Ohm values are up to spec. The mechanic will be looking for an “open” condition (infinite resistance), which reveals a defective circuit.
