I have a Whirlpool dryer that runs for a while then stops with a blinking timer screen. The dryer can't be reset by hitting any input and if you pull the plug and plug it back in it also won't respond. Light is on in the drum when you open the door, but no other sign of life. If I leave it unplugged for a period of time, which is multiple days, it runs again. May be able to get a load done, but now seems to be less than full load before it errors out.
Since unplugging will get it to work, I am assuming that there is an error condition that is causing the onboard processor to shut down the dryer (condition stored in memory) and then removing power lets the circuit drain and causes a reset. There is no error code given and checking on line the blinking screen seems to indicate a control board failure. While many things could be causing this, I looked at the board and there is a burnt pad under the relay. I don't recall this earlier, even though the same problem existed; however, at that time power resetting could last for weeks to months, so I am thinking that whatever is happening (bad solder joint?) has gotten worse and that is why it now works but only for a short time after reset.
Does this seem to make sense from an electronics POV? If the joint is bad can I run a wire from the relay lead to the power connector, in effect replacing the trace with a wire connection?
