Kodiak MK4 low function not working

[kwells]

The high setting works fine when I pull the switch to the second position but the low setting does not turn the fan on at all. Any help???

Mine's always been the same way. I think it might have a cracked board or a bad resistor.

The Kodiaks have a single speed blower motor.

High speed is full voltage going through the switch to the motor.

Low speed puts a resister in series with the motor which provides less voltage to the motor. The motor turns slower. You could have a bad connection in the switch or the resister could be bad. It is VERY common for these resisters to burn out.

Sorry I do not know the resistance and power rating of the low speed resister.

Hello,

Can you please tell me where the resistor is located and if a new one can be purchased.

Thanks

Should be integral with the switch mechanism. I replaced mine with a two position pull heater switch from NAPA. Mounts in the same place and functions the same.

So you didnt keep the original switch and just converted to a toggle?

No. The replacement switch is a 2 speed generic pull switch meant to be used on blower motors. It is NOT a regular toggle switch.

If it helps, this is the one I used to replace my Mark 3 heater switch. To the best of my understanding it is the same as the original (though I can't comment on whether the same is true for the Mk4).

That's essentially the same as what I bought at NAPA.

The switch on my Mark III was missing the resistor so I used a pulse width modulator I picked up on Ebay. Now I have variable speed control. Much nicer in my opinion. I also picked up a new blower motor at Napa. They had it in stock!
