If defective blower motor draws more current than a good motor because?
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat
Why would the blower motor on your 2000 Cherokee operate intermittantly and sometimes not at all no matter what the speed is set at?
A loose connection at the motor and/or bad ground at the blower motor. If it is getting current then the motor may have a bad spot/ high amp draw and need to be replaced.
What causes blower motor to melt fuses?
blower moter coil windings shorted, motor spinning too slow than normal (increase current draw), short circuit in wiring, excessive amp or current draw in blower circuit than what is protected by amp rating fuse for that circuit. maybe even having too many loads (electrical devices on at once) especially if all these devices are connected in a parallel circuit and power is bridged.
Why does the ac resistor overheat and melt?
Excessive curent draw, usally a weak blower motor.
What is the Difference maximum unit current draw and nominal unit current draw?
Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.
What is locked rotor?
Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.
Why does the blower fan resistor keep burning out on 99 villager?
It is quite possible the blower motor is drawing too much amperage. This is caused by a motor that is wearing out and starting to drag slightly drawing more amps to keep the motor turning. It can also have dirty wire connections at motor causing high amperage draw...
Why is motor current draw lower at full speed?
Because full speed is unloaded. As you load the motor, speed decreases, and slip increases, with an accompanying increase in current.
What happens if dc is given to induction motor?
It will draw a heavy current and coils will be brunt.
If a blower relay for a 1992 Escort is not listed as a purchasable part is there such a thing?
There may not be. Blower motors do not draw enough current to actually NEED a relay. Disconnect power from the blower and see if it will run directly from the battery. If it does, you probably have a bad switch in the dash. If the blower WON'T run with a direct connection, you might just have a bad blower motor. I pulled the blower, and it works great. I am not getting any power to the breaker or fuse box slot for the blower, that's why I was hopeful about the relay. Did you check the resistor pack located in the duct from the blower? It's located where the blower motor plug connects. I had an external wire connector to this pack that overheated and went bad, but wasn't obvious until I looked hard.
