A defective blower motor may draw more current than a good one due to increased resistance in the windings, which can occur from damage or wear. This higher resistance leads to inefficiency, causing the motor to work harder to produce the same airflow, thus consuming more electrical power. Additionally, issues like a seized bearing or obstructions can also cause the motor to draw excess current as it struggles to operate.
What else can I help you with?
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.
What current will a 100w electric fan motor draw when you plug it into a 240v wall socket?
To calculate the current drawn by the 100W electric fan motor when plugged into a 240V socket, you can use the formula: Current (A) = Power (W) / Voltage (V). Therefore, Current = 100W / 240V = 0.42 Amperes. So, the motor will draw approximately 0.42A of current.
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...
When there is no current draw and the starter does not rotate the cause could be?
When there is no current draw and the starter does not rotate, the cause could be a faulty ignition switch or a broken connection in the wiring that prevents power from reaching the starter. Additionally, a defective starter relay or solenoid may also prevent the starter from receiving voltage. Furthermore, a dead battery or poor battery connections can result in insufficient power to engage the starter. Lastly, if the starter motor itself is defective, it may fail to operate even if power is present.
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.
Why does blower fuse keep blowing on 97 Honda Passport?
The blower fuse on a 1997 Honda Passport may keep blowing due to a short circuit in the blower motor or its wiring, which can occur from frayed insulation or a damaged motor. Additionally, a faulty blower motor resistor or a malfunctioning control switch could also cause excessive current draw, leading to fuse failure. It's important to inspect the wiring and components for damage and replace any faulty parts to prevent recurrence. If the problem persists, further diagnosis may be needed to identify underlying issues.
