Excessive curent draw, usally a weak blower motor.
Overheat it!
A resistor, by itself, can not convert DC into AC.
no
yes
You can melt it and even vaporize it, but "overheat" - no.
Yes, the blower tends to draw too many amps. Too many amps in the circuit will overheat the wires and connecters and melt them.
It means the maximum power each one is capable of dissipating. The power dissipated by a resistor is (current through it)2 x (its resistance). If you exceed the power rating of a resistor, it will overheat, and that always increases its resistace value, at least for as long as it remains hot. If you take it to the extreme, the resistor can melt, smoke, crack, explode, etc. The power rating of a resistor has no direct effect on its resistance value.
Yes, a faulty AC resistor can cause the air conditioning system not to work properly. The resistor controls the speed of the blower motor, and if it fails, the motor may not operate at all or may only work at one speed. This can lead to inadequate airflow and ineffective cooling. Therefore, addressing a bad AC resistor is essential for restoring proper function to the AC system.
A current limiting resistor for ac devices.
Blower motor located at the passenger side under the dash. Probably the blower motor but you need to check the blower motor resistor and the plug to the resistor. A common cause is the plug tends to melt & short out.
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
Are the fans in front of the condenser running?
