Maytag MED9800TQ0 Won't start

[Marc Roberts]

Hi guys, I need some help. The symptom is it won't start- I've looked through all the posts I could find. I think it's the motor, or the control board.

I've taken apart the whole dryer. No codes. Tested the door switch, the belt switch. the thermal fuse is good. the motor windings seem low. The main was 2.1 ohms, start was 2.0 ohms. spins freely.  The control board doesn't have any burns or anything that looks abnormal. I also tested the P1-3 and P1-4 leads and the resistance was in spec, so it says to replace the board. I really don't want to spend 300 bucks on a board if that's not the problem, or if I can just solder a new relay on the board. I can hear the relay click when I hold start in the diag mode.

my question is: how do I check the control board, the motor relay, and the motor?

Thanks in advance,

Marc

If the motor power relay is in the beginning stages of a solder joint failure, it may not be burnt yet, look for what appears to be a human hair wrapped around the solder joint- your symptom description sounds like a bad relay, they can develop scorched contacts internally, and 'click' without triggering the 120v. I would put my meter leads into the connector at the motor and check if it is receiving voltage when you press start, no voltage? replace board. Voltage but no movement? replace motor. You can have boards rebuilt for less than 300 bucks at the major refurbishers, and they usually come with a year warranty.

A company called Corecentric is typically who I use for rebuilds.

You may be able to repair the solder joints if they are broken, I've fixed a few this way. just heat the joint with a small bit of soldier

Thanks guys! It was a bad solder joint at the relay, on the back of the board. It was completely burnt. I couldn't see it until I removed the board. Re-soldered, and BOOM! it worked!

Thanks for the info on the rebuilds. I think de-soldering and re-soldering a new relay would be pretty easy to do yourself. Anyone know where to find the relay? In case mine has issues in the future. Thanks a lot.

Radio shack or if you get the number off the relay you can google search it.
