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

Buenas, tengo un problema con mi Pool Up, el motor de movimiento funciona puesto que le ha aplicado 15 voltios externos y el motor gira, he comprobado la tensión en la placa y da 10 voltios por lo que no puede mover el motor de movimiento, no se si a alguien le ha pasado y cual es el componente de la placa electrónica que esta causando dicho problema gracias por vuestra colaboración. El otro motor funciona perfectamente y gira la helice.

by: Anonymous

Hello,

I have a 2410073LF Rev 02 Board and there is a 18Ohm 1W Resistor.

But can someone tell me which value has the R3 Resistor next tu U6?

Thank you.

Does anyone have information on what models/motors these fit by rev #? Will an 2410073LF-rev 2 work for rev1 or rev 5 for rev 1 or 2? Someone told me each rev # had a different program.

does anyone have or know how to troubleshoot this board? i have correct power to board and no output to either motor. led on board never comes on. Nothing looks burned. with power to board should i be able to measure power to motor connections with them disconnected?

If that resistor is burned, you can be sure that some transistor is burned too.

starstarstarstarstar 		R38 keeps burning out on 24100075LF board
by: Rolf

Does anyone know what causes R38 to burn out on the 2410075LF diagnostic board. I’ve replaced it and it burns out as soon as I apply power to the board. The unit is a 6 year old Dolphin Supreme M4. Any help greatly appreciated!

starstarstarstarstar 		F1 Fusible resistor burned
by: Gerard (The Netherlands)

Hello,
Does any of you still have a picture of the PCB
2410073LF
This fusible resistor F1 is burned so I can not determine the colours, I assume it must be a low resitance, say 0.1 ohm
Many thanks.

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

starstarstarstarstar 		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

by: Dan

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!

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.
