Ok pulled off control after loosing up bellow tube . From what I can tell everything looks ok but checked screws holding wires to contacts and even lifted wires to make sure they were in good shape. Cleaned contacts a little just to be sure put back together, no change ! There seems to be some oil under the control and also one screw was missing.

While you were under there to you should have checked the resistance of the start and run windings. You should also check and see it any of the three are grounded. It's behaving like my recently departed DR35 with bad windings.

I assume the three contacts are the start and run windings ? The run contacts are the ones down under on control?

You have to look at the DR manual to determine what is where. Two of the wires are the heater. The other three and run, start and common.

I'm loving this thread since I have a D2-A16 myself. Mine is in better shape since it's running. Looking at the terminals on the control I'm assuming that the three adjacent terminals are for the compressor windings. Others will confirm this. Anyway, to check the windings use an ohm meter. You're trying to identify the start, common and run windings. To do this take readings of all combinations, take notes of course. The greatest reading will be between the start and run terminals. The lowest reading will be between common and run terminals. And the third reading will be somewhere in the middle, that will be between the common and start terminals. To be sure you're right the two lower readings added together will equal the greatest reading. If there is no reading between any combination that is a bad thing. Hope this helps. GO D!!!

Glad you like the thread that's why I like to post so everyone can befit ! Ok going left to right on contacts buy the picture numbered terminals 1 to 4 1to 2 6.3 and climbs 1to3 7.8 and climbs 1to4. 3.6 ohms 2to4. 9.2 and climbs 3to4. 5.7 ohms 2to3. 7.2 and climbs Took each one to ground 1. 9.7 ohms 2. 4.8 and llimbs 3. 9.8 ohms 4. 6.7 ohms
Terminal 2 must be on heater sense it climbs Looking at page 40 in dr manual it shows a base plate that looks like mine my view was from behind this one is looking down from front of machine so my numbers would be from right to left by this pitcher .

I think I have a picture from the DR manual which says what is what. Probably the same one you looked at. Looks like you have continuity to everything at least. Must mean that the problem is in the control and not in the motor fortunately.

You need to isolate the three to the compressor and ohm them out. I would have to look in the manual to see which ones they are. Once isolated you can ohm them out properly.

The unfortunate part of his readings are that he is showing continuity on all terminals to ground, a bad thing. I'd think that the most optimistic scenario is that there is an issue with the insulation on the wiring. Unless, of course, that I'm interpreting what he noted incorrectly.

There are no short cuts. You must lift the heater leads and check the resistance. You also need to check if any of the three motor leads are grounded.

Grounding would cause the start contact to not function and the overload would trip. The DR35 did this.

Ok thanks everyone you all gave me very good info!!! ckfan that looks like page 40 in the dr manual thanks ! Agree with Tommythecube you would think there would be an open to ground on all terminals. Or at least very high thanks for your response!
But I think coldspaces & Travis are right have to isolate motor leads and take a reading. Whitch won't be hard sense I have control already lifted off. I will lift all three and isolate then take a reading! Just to let everyone know I picked this dr up out of a one car garage and it had some oil on top by control like some one may have spilled oil on it or it was run off from cans being set on it . When I pulled up control wires they were not soaked but definitely not dry. Being this is cloth insulting material I can see it soaking up oil !!! Thanks again for your help well post after I have isolated motor wires and taken reading. Happy Thanksgiving !!!!

Hi everyone hope your thanksgiving was good!
Ok isolated the moter wires ! com to start. 7.9 ohms com to run. 3.3 ohms start to run. 5.5 ohms
run to ground 5.8 ohms start to ground. 9 ohms on the start to run the meater was moving around so took the meddle reading .

The good news is that you gave good windings. The bad is that it's grounded out and it dead.
