Bad Blower Relay Symptoms at Marie Linnie blog

Bad Blower Relay Symptoms. If the blower motor relay goes bad, the ac system cannot pump any heated or cooled air through the vent. Then, inspect the relay for signs of damage or corrosion. Whether you’re dealing with a lack of airflow, inconsistent blower speeds, or no operation at all, the issue often boils down to either the blower motor itself or the blower motor resistor. Symptoms of a bad blower motor relay on platforms where the blower is directly controlled by the switch rather than a module, the relay will cause the blower not to work at all, which means there will be no airflow across the evaporator, and the effect will be the same as the a/c not working at all. The blower motor may operate inconsistently or intermittently when the relay is failing. The blower motor relay will inevitably wear out over time. Furthermore, it can cause an inconsistent or intermittent fan speed, leaving you without proper airflow. Common symptoms include inconsistent fan speeds, no response from the fan, or unusual noises when the fan operates. Symptoms of a bad blower motor resistor. Symptoms of a bad blower motor relay inconsistent or intermittent operation: What steps should i take to diagnose a bad hvac fan relay? The various airflow settings may also fail to work or you may not get any air from the vents. The blower motor’s relay monitors the current used to power the blower motor and is continuously turned on and off. When the blower motor resistor goes bad, the motor can get stuck at one speed. What happens when a blower motor relay goes bad?

The blower motor may operate inconsistently or intermittently when the relay is failing. What happens when a blower motor relay goes bad? What steps should i take to diagnose a bad hvac fan relay? Symptoms of a bad blower motor resistor. Understanding how to diagnose these components can save you time, money, and the inconvenience of unnecessary repairs.
