Fujitsu ASU9RMLQ Thermistor
In an HVAC system, a thermistor is a certain type of resistor which has a resistance that will fluctuate depending on the temperature. They notify the heating and cooling system when the temperature reaches a certain point. The heating and cooling system must know the temp in a few critical areas to do its job as it should.
Important signs your thermister will not last the year
- The AC and heat system may never start up because of the bad thermistor
- Blower fan could never begin in its attempt to ramp up the airflow

Before buying or purchasing a replacement thermistor for your Fujitsu ASU9RMLQ do your best and cross-check the model number and also make a visual comparison so that you are positive that the correct replacement thermistor is the one being purchased. There is no rule that says you have to install the replacement part alone. Search for a pro in your town or city to replace the part.
