What does the thermistor do on an AC system?
Average rating from 849 customers who received a AC is not working Inspection. An AC thermistor is a type of temperature sensor that is commonly found on modern AC systems. They detect temperatures and send a resistance signal to the AC control module so that the automatic adjustments can be made to keep the cabin at the correct temperature.
Where are the thermistors located in a car?
As they are basically ambient temperature sensors, they can be found both inside the cabin and underneath the hood of a vehicle. AC thermistors read and interpret data on temperature that is critical to the proper operation of a computer controlled AC system, such as those found on most modern vehicles.
How does the Spyder control multiplex system work?
Below is when we introduced the Spyder Multiplex System in each model. There are two terminator resistors installed in each network. We solder them right into the circuit board keypads. There is a diagram included in each motorhome’s manual to show you which switch panels contain the terminators.

How can I check the resistance of my thermistor?
Let’s check the thermistor wiring harness. Plug the thermistor back in. Remove the 13-pin connector from the electronic control board. Put one meter lead on the gray and black wire and the other on the red wire. You should measure the same resistance that you measured directly at the thermistor at room temperature.
What should the thermistor read on a Dometic thermostat?
Please note that this board has a thermistor compensation adjustment ( yellow arrow ). The following is the Dometic method for checking the thermsitor. With the thrmistor disconnected from the circuit board, and in a container with ice and water, the thermistor should read 7,000 to 10,000 ohms.
