Fan speed control is not working Inspection Service

The most likely cause of fan speed control failure is a resistor failure at the fan’s motor, although it can also be a defective control switch or burned-out fan motor.

Common reasons for this to happen:

  • Blower resistor malfunction
  • HVAC control panel is bad
  • Blower motor is bad

What to expect:

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.

First let me talk about YourMechanic overall. The transparency of the website, being able to see what the prices are upfront—being able to see the estimate for hours and parts before any work has started is refreshing and instills trust. The second thing is the convenience—being able to have someone come to your home and work on your vehicle where the car is sitting right there is extremely convenient. Now my review of Paul: Paul showed up on time, but when he pulled up to my house with a gorgeous trailer that had every top-notch piece of equipment needed to repair my vehicle, I was blown away. Paul had a carpet to lay on to prevent from getting dirty, he had a shade canopy to keep himself out of the sun, he took photos of my vehicle and of the old parts, Paul showed me the brand new OEM parts, which were still in the box, he event went so far as to answer all my questions on how struts work and other various repair questions. Paul is definitely in a league of his own. He is professional, extremely qualified, and honest. In short, Paul is a Master Mechanic! You can't go wrong hiring Paul to do your repair work! Thanks Paul! See you Monday to take care of the additional repairs you recommended.

Ryan was very helpful in getting my car up and running. He came out on time, and didn't waste any time getting right to the task at hand. He had a very professional approach, and knew exactly what he was doing. By the time he was done, my car was running better than it did when I bought it. He is a very skillful mechanic who clearly takes pride in his work.
