R38 Burned 2410073LF Rev 01 Control Board

by Dan
(Savannah, GA)

The R38 resistor on the control noted in the subject is burned out.


1. The unit is 5 years old. What causes this resistor to burn out?

2. What is the resistance and wattage of the resistor. I can not make out the colors due to the burning on the resistor case?

3. Based on some other write ups on burned out resistors on these PC boards, I believe this is either an 18 Ohm or a 0.1 Ohm resistor.

Please provide me with some assistance.

Thank you!

Dan

Any fixes yet? I tried the previously mentioned resistor (18ohms, 1%, 1/4 watt) but it burnt as soon as power was applied.
Any help would be appreciated.
Thanks,
Kenny

R38 value 2410074LF REV 03
by: Andy

Hi there, I have a slightly different board number which has an R38 resistor that is unreadable. It appears to be the only component damaged by a lightning strike.

Issue is that I have replaced this with an 18ohm 1W resistor and it burnt straight away - without any of the motors connected...

Wondering if the wattage of this resistor should be increased??

Appreciate any thoughts out there!

Cheers, Andrew

R38 Resistor Value

Dom,
The picture of the board is too large to post from my iPad.
I will try again from my iPhone.
Send me a picture of your board if you can.
What is the number on the back of your board?
Do you have an R38 Resistor on it?
If so, what are the colors.
Thanks!
Dan

Resistor

If you can post a picture that would be extremely helpful, I can check my burned board as well. Many things can happen as to why it burns.

If you're interested in selling the burned board in looking for one :) accidentally got water in mine.
