Kelly (mixfinder) came through town on his way to visit family in Kansas on Friday. We spent most of the day talking, baking, washing and pouring over magazines and brochures of appliances gone by. Ben came in Friday evening and we had a small dinner party of lasagna and of course, baked goodies by the masterful hand of Kelly!

We went to a couple of estate sales, the farmer's market downtown and thrifting on Saturday morning. Ben and I nearly fell over when we found this - 1987 Whirlpool DU8900T dishwasher. What a minty-fresh machine this is - just a tiny bit of hard water in the porcelain tank but otherwise in beautiful condition.

The money-shot. Very nice shape. A bit of touch-up on the rack vinyl needed and it should be good as new. Our garage-testing revealed it works perfectly. I've always wanted a Whirlpool to play with as I've heard so many good things about these Power-Clean machines but have only ever had one of the axial-motor, wash-tower BOL units.

Saturday afternoon, Kelly departed for Kansas and Ben and I set to work on my Maytag combination washer-dryer. There was a catastrophic electrical disaster with the 240-volt side of the timer and the last time he was here, we took apart the timer and spent more than a few hours repairing and rebuilding it with JB Weld, tiny washers and new rivets. Looking at the repair, one might think it was a death-wish to plug it in again but we felt confident that it would work. With the crucial help of Cory's electrical analysis, we put relays in the heater circuit to keep the current out of the timer in hopes of preventing another meltdown. The current for the heater runs not only through the timer, but also the fabric/machine control switch on the panel and even the end-of-cycle chime! Ben will likely share more of the pictures from the process, but here he is on the floor disconnecting the line from the terminal block behind the machine.

wow Greg
Your new kitchen is georgeous, can't wait to come play there.
And I am so glad you got the Combo up and running again, that is such a unique machine and a terrific color too! Now its bearing time for you no? I just had the motor stop in my TOL Bendix Duo this month so that has to come apart next month. If it isn't one, its another!! Cheers jon & artey | ||

So - back to the Combo. This story starts last spring when Greg noticed a poof of smoke from the Maytag Combo! In September of last fall I headed to Omaha to then pick up a different Maytag combo in Kansas. Over that weekend we tore into Greg's timer.
What you see below was the handy work of some pretty intense current for the heater assembly. The terminal board should not look like this! Ultimately the chime circuit (15) is to blame here as full 220v runs through this area of the timer when the heater is activated.

For the most part, this timer was toast (no pun intended).
We figured it wouldn't hurt anything to try and repair the terminal boards with some JB Weld, which would cure to the fibers of the board and keep the contacts and terminals in place. Otherwise the other two solutions would be to: 1. Find a new timer. Doubtful. 2. Have the terminal board rebuilt from scratch. Can be done but would require the work to be farmed out (or just part the machine out and donate the boot to me) Somehow the JB Weld, along with some precision washers procured from the awesome Ace Hardware by Greg's, ended up being our saving grace. It may look sloppy in this photo, but it worked!!

Over the winter we had Cory take a look at the Combo wiring to see if we could remove the heavy 220v current from the timer and push button assemblies. I wanted as little of current as possible to pass through our JB Weld handy work.
After some well placed questions on how the machine worked, etc., Cory came up with the following solution. Greg and I omitted the Chime SPDT relay for now as we wanted to see if we could get the timer working on the SPST heater relay.

Fast forward to August 2010
Fast forward to this weekend: the next task was getting some relays to work in our favor. I found a great Power Relay from Grainger that fit the bill perfectly.
The SPST relay for the heater ended up being a Grainger part number 5ZH37, Omron PN: G7L-1A-TUB-J-CB-AC200/240. The chime relay was a Grainger 1YDD7, or Omron PN: G2R-1-S-AC240(S). Fit perfectly next to the fabric selector.

Is there a piece missing from the base of the maytag combo? What would it originally have looked like? | ||

Stunning, Dazzlling, Riveting and Mind-numbing
With skill like that, certainly you gentlemen could have solved the Gulf oil leak if anybody had bothered to ask you!
Great to see Kelly out and about, an inspiration and hope to all of us, especially me. Many thanks. Yes, Ben, 220 volts and that electric chair headgear contraption is SCARY, very scary, but exciting and fun nonetheless. DZZZZZZZT | ||

Let me get this straight
The SPDT relay either engages the Chime at the end or the other side of the 110V during dry.
The SPST engages the other leg of the 110V and when both are engaged it delivers 220V through the relay. Are the "x"s where you added split contacts or places you cut the timer block out of the 220? And you found a double block relay with a SPDT and a SPST in one box??? | ||

Jon -
I can't quote Cory directly, so hopefully he chimes in; again, no pun intended, LOL. for now, Greg and I did not hook up the SPDT relay for the chime as we wanted to test to ensure that everything would work with just the relay for the heater. I ordered two individual relays according to Cory's specifications on his modified schematic. Greg and I removed the blue wire running to 15 to effectively remove the chime from the cycle; so yes, our total reconstruction of the timer still has yet to pass the test when speaking of contact 15. However, I did a continuity test of the contact for 15 prior to installation to insure the future installation of the SPDT relay for the chime installation, and it passed with flying colors. Considering it will only carry 300 miliamps (per Omron's specs) compared to 20A over 220v, I am not as concerned about it as it would be if we hooked it up to factory specs. Thankfully those contacts were cleaned to a spit shine! :D You are correct though on the X's blocking out the timer from receiving the full brunt of the heater's full draw during heat, in accordance from what I understand with Cory's previous explanation. He really is the true genius behind this fix. A HUGE thanks again to Cory for this one - I would not have been able to do it without you buddy! Ben | ||

John and Jeff have always used a "heat relay" to take the heater current out of the timer during dryer and combo restorations. With the Filtrators, you can hear when the heat cycles because of the SNAP! of the solenoid, same when the LK combo went into cooldown. | ||

HEAT RELAYS FOR CLASSIC ELECTRIC COMBOS AND DRYERS
As Tom said mentioned my brother Jeff and I have been installing heater relays on classic machines for at least 25 years. We normally try to bypass the timer, the temperature or program switch and the motor centrifugal switch these are all parts that are difficult if not impossible to replace on classic machines. You should not ever bypass the heater safety thermostat in case the relay contacts ever stick, that way you have a safety backup. I usually get a relay with a 208-240 volt coil and an contact amp rating of at least 30 amps at 240 volts.remember thier is no 220 power in this country most homes have 230-250 volt power if you have single phase power, many commercial buildings and apartments and condos have three phase power in which case you end up with just 208 volts which ends up producing 25% less heat than 240 volts.
