Good point. I forgot about that. Check for 12 VDC on the dispenser board J1-1 - J1-3. Check the Keypad keytail. Disconnect it from the board and check for any corrosion on the pins. I haven't found any way to test the keypad and the Lv board is discontinued.
BTW thank you for your excellent technical skills. I am a 60 Years old. A US Navy Submarine Interior Communications Electrician. I started HillBilly Appliances and more after I retired from many Industrial electrician jobs as a civilian. I truly thank you for your help, and God Bless you.
I do this here in Lamar, Mo. just for extra money for my wife and I.
I will do as you say and keep you updated on my progress.
We got a lot in common my friend. US Navy 1972 -1976 Aviation Ordnance 3rd class. There wasn't a lot of openings for someone with bomb, missile, or weapons experience so I went into appliance repair. Surprisingly similar to building guided missiles....lol. 66 years old.
Good question. I don't know. Service techs don't go beyond board level in the field because it's not cost effective. That being said, many members, mostly those with an electronics background, have replaced board components with some success. The only boards I've worked on were on my own appliances. Before the internet I thought a "blown cap" was what's left over when you shoot a cap gun. lol
I got out as a E6, was an LPO , qualified as a Diving officer when I left. anyways. I did solder the Capacitors on the main mother board in a repair kit I got off Ebay. Same old same ole. I am going to sell it for 200 as a garage refrigerator. my only concern is, will it stop running when it reaches operating temperature?
