Have you tested them now that they're off the board?

 

Have you tested them now that they're off the board?

Not yet. I had to use my meter to try and determine which relay went to the drain pump assy.

I could not find a schematic or part layout for this controller board. I called LG support (offshore) and even though the guys tried to help they admitted what I was doing was above them and they did not have the knowledge or drawings I needed. They suggested I call a service technician however they would only order the whole board. I am on my own with this one. I just need to source the relays.

 

The relay removed has a 12V coil and spst contacts, it can easily be tested out of circuit to prove it.

 

I just need to source the relays.

One method is to go to a site that sells multiple makes & sizes of relays such as DigiKey and go through the likely suspects until you find the right footprint/rating, even if you do not have access to Digikey you could find alternate part No's.
I would think there are other makes out there with a similar/same relay.
Max.

 

I would remove the cover on the relay, then if possible see if the contacts are moving.

The relay has to be driven, usually, a transistor, having received a signal from its brain.
Good luck, Keep us posted please.

 

Won't receive the new relays until last week of December as they are coming from China.

 

Anyone know where I can buy these relays or their equivalent?
HF33F/012 -HSL 3

This is very likely just the Chinese clone of a pre-existing standard market relay. I'm looking on digikey for a plug compatible but higher amp version.

 

So far, I'm finding that Omron makes compatible relays that Digikey has in stock

Hi i like to know if you fix it ? I got the same problem with the washer relay

hello did you fix your problem with your washer because i have same problems with my washing machine and i don't know what to do

 

I doubt he will ever report back, 80% do not. Besides, that is not how you troubleshoot devices. It was just guessing.

 

There appears to be many sources, ebay etc, if you locate the SPDT version, you can just cut the N.C. pin off, to make it SPST.
Max.

=================================
This board looks like the LG control board I have been trying to tackle. I have no power at all. There was a blown fuse on the board itself right next to AC power input. . I dug the fuse out and replaced it but that didn't help. Well at the present moment I decided to check the resistance on the three pins that go to the bldc motor. It is clearly in Mega ohms. on 1 and 2 and 3 and 4 but in kilo-ohms between 1 and 3. I am assuming the IC under the heatsink along with whatever resistors are there are toast. I don['t know why nothing comes on at all. Push the button on the user interface and nothing. Not even the little LED on the PCB light up.
... It would be nice if these people... whoever they are. from GE to Whirlpool to Samsumg to LG and whoever else sold complete repair techincal book so I can pay them and buy them. All you find is parts changing. And obsessed people like me don[t have a prayer to have access to the knowledge. They want the masses dependent. A untold slavery. Chinese labor, cheap products, fill the landfill, buy new ones.

 

I would love to no if those relays were the problem I’m having the same trouble..

 

Are you OK to remove the relays? as in Post#18
For testing purposes, a relay of the correct voltage can be used, wired extensions from the relay to the PBC.
Safety: Make sure it is well insulated from the other components while testing.
Please update us on your progress.
Good luck .................
