Cause and effect, timer bad, because motor shorted

9 posts in this topic

Sharpining the axe here.  Will a motor shorting out cause the timer to fail?  . Need to get this cause and effect info.  Bad timer I have so need to test motor winding and circuit before installing a replacement timer.  I noticed on the plug connector going to motor that blue wire terminal has burn spot.  Any wisdom greatly appreciated.  Looks like appliance repair is going to be my bread and butter for a while.  If you can refer me to some post on do's and don'ts or advice please post.

Washer Motors don't usually "short"

(unless you can visually see burned Motor windings)

May just be a bad connection on  the Motor blue wire ..

Does the Washer Agitate, Spin, Motor hum ?

It does nothing, dont have power out of timer to any motor leads,  watching a vid, the guy said you may be replacing the timer, because a motor shorted or the timer failed.  Hmm I thought, motor shorted and fried the timer, back feed of current, since there is not any circuit protection between the two components, that could be.  I was checking this out last night before it got dark, going to go check out motor readings in a few.  Took some good notes.  Trying to get some proper checklist to follow.  Cause and effect.  Bad motor, will cause a timer to fail, so check the motor and ???? before installing a 115.00 timer.  In the industry we are supose to check out the system before resetting circuit breakers, most techs just reset and hope it works so they don't have too.  Fuses are cheap, but timers are not.  Thanks for response going to shop will check back later.

  Shorted motor windings are rare. The burnt wire terminal is caused by bad connection at terminal. Bad connection means resistance, current through resistance produces heat, heat burns contact and/or wire at that point. Motor circuit is protected by breaker for wall socket as well as the motor thermal overload. If motor winding is shorted to ground, panel breaker is the only protection. The best thing to do here is first to fix the bad terminal. Install new timer, place amprobe around motor feed wire and start washer. If it draws over 10 amps, there is a problem. Motor contacts in timer are rated for 15 amps. You will notice the sticker on the timer that shows the connections, some terminals have a + next to them and others have an The ones with the I are rated for 15 amps, ones with the + are rated at 10 amps. A dead short in the motor would trip the panel circuit breaker immediately. A partial short would draw excessive current which you would see on the amprobe so you could shut washer off before any damaged occured to any timer contacts, lid switch contacts or pressure switch contacts.

Thanks for info. Tested the motor windings, no issue there, I was getting no power to the motor, started checking connections, took connector off of timer. Took the motor switch off and discovered it was not like the old style.  Hmmm getting more lessons.  Wire colors going to motor all diffrent, more notes taken and scratching of head..  Lol. I had taken water pump loose snd spun the motor.  I decided to try it again and, it works now.  Ran it several times and it doesnt malfunction. Applying rule # 1 if it works dont' mess with it..  I posted on here asking if anyone new of a good book that has info on electrical and mechanical  appliance info,  The post got moved and I can't find it.  Have you ran across a good book.

Just an update on the problem with this washer, was a china made motor, blue terminal was showing burn spot, motor burned out, had to replace the motor.  Would check out good in the shop but when installed in a house it failed.
