Kenmore/Whirlpool dryer F01 fix

[bdcardinal]

We have maybe a 15ish year old Kenmore HE3 steam dryer that for the most part has been trouble free. Last week it started giving an F01 error. I looked some things up and it all pointed to a main control board failure. I watched a video where it showed to re-solder and add a jumper wire to even the load. This seemed not the greatest advice, so I did some more research and found this video showing to desolder the relay and solder in a new one. Now I haven't done any soldering in a long time so my skills were rusty. I found a relay on Amazon for $10 which funny enough was described as Kenmore/Whirlpool F01 repair. Used my new Milwaukee M12 soldering iron and went to town on it tonight. Now my skills aren't the best at all, but I got it all done. Plugged it back in and it started right up!! Even if this only works for a few months, it fixes a machine and buys us time to pick out some new ones.

My terrible soldering skills:

A penny saved is a penny earned. Who cares how the soldering looks, the task was accomplished. Bravo!

I sure do like the very old machines which had no circuit boards to burn up like that.

Those you tube videos sure help in solving problems.

That may buy you another 15 years.

You are not giving yourself enough credit on your soldering abilities! On that burned terminal/circuit board trace, you might want to rub off some of the protective coating over the trace to expose some shiny copper near the relay terminal and apply some solder there and bridge it to the terminal to ensure a better electrical connection.

How do you like the M12 soldering iron? Been looking at that one lately.

It worked well, well worth the money. I have a bunch of M12 and M18 tools so I added it to the collection.

good for you! modern appliances have too much electronics IMO! girlfriends lightly used whirlpool front loader needed a $500 circuit board new simpler machine was CHEEPER!!

Must be an electric dryer at the heater relay.
Corecentric Solutions is a resource for appliance boards, they are a rebuilder of older boards. I've installed a lot of their boards in my previous life.

That does need to be bridged with a wire. Much of the original copper trace has burned away.

Take some #18 bare copper wire and solder it to the terminal points at both ends of the copper trace, routing it over top of the existing copper.

Failure starts because the machine process at the factory doesn't leave enough solder on the connections. They crack and burn. Reinforce all the high-current connections on the board by applying additional solder.
