Maytag 1974 A107 transmission?

[dogstarb52]

Okay, I am new here. My old girl will not agitate. It simply fills, then stops. However it performs other functions once manually advanced past agitation, wash cycle. It drains wash water, fills with rinse water, it spins to damp dry. the timer advances automatically except at agitation cycle. I tried advancing it manually into the wash cycle without any success at agitation cycle. Is this due to transmission failure ? I have not disassembled it beyond removing the rear top panel, inspecting the timer assembly and cleaning the contacts and timer control shaft. I have yet to find an exploded diagram of parts, a schematic or any repair information.
I appreciate any advice...
Thanks

If the TIMER stops in 'agitate' as well as the motor, three things come to mind. The wire fell off the normally-open contact of the fill switch or at the other end where it goes to the timer. The fill switch itself has failed. The timer contact for 'agitate' has failed.

There is no way the transmission could tell the timer not to run, so it's not that.

motor not reversing?

or humming while trying to agitate?

Agitation, A107

No noise, no humming, it just stops filling, then stasis, no function in wash section of timer circle, it is as though there is an absence of electrical signal ?

This is definitely an electrical problem.

 

Could be a burned timer contact, could also be a burned contact in the pressure switch, could also be a loose or burned off wire AT the timer or the pressure switch.

 

If the motor runs fine for spin it's not the motor. If it were the transmission you would be hearing and smelling fascinating things when it initially tried to agitate.

 

How handy are you with matters electrical?

Agitation, A107

I have no schematic or any sort of reference for wiring, repair, troubleshooting, but the all the wires look to be connected. I know not which wire might signal agitation. I need to move the heavy ol' girl to a better place where I can inspect the lower sections. I have not inspected it below the timer panel area. I guess there is a wire dedicated to the agitation mode from timer down to motor/transmission/brake area ?

 

[kenmore71]

There is not a special wire for that and there really should be no need to remove the lower panel, EXCEPT that the wiring schematic is glued to front of the outer washtub! For your convenience I will print it below:

Electricity ?

I shall try electrical connections next, but I am better with mechanical stuff, although not that great at any of it. I have experince working on stuff, fixing cars, stuff around the house--a jack, no master. I have cheapo voltmeters--ohm, low amperes, but I have no reference. The paper one from the old machine is long gone.

 

[kenmore71]

The first thing I would do would be to remove the BROWN wire from the water level switch.

 

Then I would jumper the two Yellow with Black stipe wires across the pressure switch.

If the machine starts to agitate then it is this switch that is bad. 

 

If nothing happens, then there is likely issue in the timer itself.

Agitation, A107

Thanks, Doc!
I shall try to check stuff in my own feeble and bumbling way, hah?!

 

[dogstarb52]

Agitation, A107, Si, Si, Si! Eureka!

Okay, Doktor Kenmore, Know-more, Millionen Dank, Monsieur!
I joined the upper yellow/black stripe wire with lower gray wire from their connections at the water level switch, et Voila! Agitation occurred by ol' '74 A107 Maytag, not May Day!
What is next? I should replace the water level switch ?
My old machine has only three wires at water level switch--facing front of Maybelle, upper right brown wire, upper left / middle yellow & black stripe, below is the gray one. Maytag P.N.# 205337, discontinued new, used ones on ebay. According to the Ohm test, it passed, but your test showed it to be the culprit...

Agitation, A107

Where is the lower end of the water level switch pressure hose ? Tub rear ?
I removed the front panel and found the schematic on the floor in front of the tub. I could not see where the tube ends. I cannot find any parts diagrams.
More to come

No agitate

I wonder if the switch/contacts on the motor itself are bad. If that is the case I don't believe those switches are still available. The experts will know. I suppose replacing the entire motor with switch contacts will be the fix. BOTH My A806 and and A712 have defective trannys and neither will agitate.

 

[kenmore71]

Seriously, folks, do you read the previous comments before you speculate on what needs to be done? If the motor contacts were bad the machine would neither spin NOR would it agitate when the pressure switch was jumpered.

 

Paul, you will need a replacement switch to begin with. New or used probably doesn't matter but you MIGHT get more life out of a new one. There is no need to find the other end of the pressure tube unless for some reason you have cracked or broken it removing the old switch. The pressure hose just slips onto the switch. The fact that it stops filling at the right spot tells me that the pressure hose is good.

 

Your ohm meter reading is most likely irrelevant unless you took it across the two terminals that were connected to the yellow/black wire and the gray wire with the tub FULL of water. Nonetheless, if it agitates by jumping these two terminals it's the switch. 

 

I just emailed the parts list to you.

water level switch testing

Thank you greatly for the parts list, Mark!
If anybody out there in Oldtimer Maytag land has a new old stock water level diaphragm switch Maytag # 2-05337 / # 2-3362, please, let me know. I bought a used one off ebay which is not here yet. I salvaged one from a parts' 208, but have yet to test it in the machine. I guess the diaphragms wear loose over the years. The relay in mine actually clicks when I blow into it, but quits when I quit. 1974--the old girl ain't what she used to be. I found one new one from Canada, but I am not ready to pay $90 with shipping included, eh?!?
You know how many Paul Nelson names there are in the Minneapolis phone book, a short paragraph among the pages of Nelson names.
Again you are correct, Herr Kiefer!

There is no holding relay in the water level switch.  Air pressure on the diaphragm triggers the contacts as the tub fills to the proper level.  Pressure must be maintained for agitation to continue.  The contacts disengage when the pressure releases (the tub drains).

Maytag A107 1974 model, no spin

I replaced the water level switch, renewed the tub seal / rubber gasket, replaced the belts. I removed the pump hoses to check for any blockage, all clear, I think. The pump turns and drains, but not completely, probably because it will not spin. It made it through the regular cycle with agitation, except for spin / damp dry. The motor runs the belts, but the main pulley does not turn with the belt. I managed to complete the wash cycle with most of the water drained and somewhat rinsed. I makes some squealing sounds, the main drive pulley is hot and it smells of burning rubber belt during spin.
I tried to oil the main pulley and brake, as well as the pump.
I guess the brake is stuck ? I see no oil leakage from the main drive pulley area.
I am ignorant as to what to try next, other than give up ?

Maytag A107 1974 model, no spin

Could the lack of spin be due to failed tub mounting stem and tub bearing assemblies?

hat to try next, other than give up

You gave it a good try. The A107 is a BOL machine, I wouldn't waste anymore time or money on it at this point.

Here is a nice mid-80's Maytag A612, in your area, good price too, I'd jump on it. Parts from the A107 will interchange and you'll have a newer, near TOL large capacity machine to work with.
