Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! If there was visible issues with the timer, it may be that there is an excessive current draw and it may have damaged the thermostat. Does anything come on, like the fans or the cabinet lights?

Customer: replied 10 months ago.
Nothing has come on since I replaced the timer. Since then I have taken out the thermostat and jumped the wires to see if I could get it to start. Nothing. I have not bench tested the thermostat yet. I left the fan delay thermostat intact. Could it be causing the problem also? Also if I get to the point where I will require a repairman I guess I will have to call GE as the ones I have used in the past no longer work on GE.
Customer: replied 10 months ago.
I am kind of frustrated that what I perceived as a simple repair (clogged defrost drain) has snowballed to this. The unit was working and cooling fine up to this point. Water leaking down from defrost tray was only issue.
Customer: replied 10 months ago.
Oh. Very important. You asked if the cabinet lights come on. YES.
Customer: replied 10 months ago.
When may I expect a return response?
Expert:  Kelly replied 10 months ago.

What is the defrost timer part number you installed? Have you manually advanced the new timer to see if it kicks on?

Customer: replied 10 months ago.
Part # ***** the timer TMDJX35RB9. Ge part # ***** replacing WR09X0413. And yes I did try advancing the timer.
Expert:  Kelly replied 10 months ago.

Thank you. You installed the incorrect timer. You need to install part number WR9X502.

Expert:  Kelly replied 10 months ago.

We need to start there and move forward once that is in place.

Customer: replied 10 months ago.
I don't see how that is possible. The timer I installed is the same exact one I replaced. I literally handed it to the parts guy and he gave me the exact same one. All the numbers match. Since you replied I checked the technical data sheet stuck in the refer and it calls for WR09X0413. When I Google that number it says it is discontinued and replaced with 502. But if I replaced the same exact timer why would that make a difference? ? This is very frustrating!!
Customer: replied 10 months ago.
Plus when checking the cross reference of 502 it says nothing about replacing 413 or 483. Are you saying I've had the wrong timer in my fridge for 16 years?
Customer: replied 10 months ago.
when I enter my refrigerator model # ***** sears parts direct it still calls out 483.
Expert:  Kelly replied 10 months ago.

Are you sure you have given me the correct model number? See the GE lookup for the model you provided below. Number 257 is the timer.

Customer: replied 10 months ago.
I gave you the correct model #. This is going to go nowhere fast if you treat me like an idiot. I understand all that and see that it calls out 502. But you're not reading what I'm sending or something. IF I REPLACED THE TIMER WITH THE SAME EXACT ONE WHY SHOULDN'T IT WORK?? Plus Sears parts direct calls out 483. ( As I said before.)
Expert:  Kelly replied 10 months ago.

Wow, I am not sure how you came up with that but I am no longer interested in helping you at this point. Perhaps another will help, good luck.

Expert:  Appliance Guru replied 10 months ago.

Hello, I am a different tech

Does the unit work with the old timer?

Customer: replied 10 months ago.
Please read ALL of the original material and transcripts and get back to me. The original timer was visibly damaged/discolored and when I removed it one of the connections came off near the point of most discoloration. That is why I replaced it.
Expert:  Appliance Guru replied 10 months ago.

OK get a jumper wire and connect terminal 3 to 4 on the defrost plug. That should turn on the compressor if not you have something more wrong with the unit.

Customer: replied 10 months ago.
That did not work.
Expert:  Appliance Guru replied 10 months ago.

OK if you jumped 3 to 4 and the compressor did not come on nor the fans you have something more wrong with the unit besides the timer. You need a volt meter to do some further checking

Customer: replied 10 months ago.
I have a 7 function multi tester will that work? If so what do I set it at?
Customer: replied 10 months ago.
You know I have bypassed the defrost thermostat at this point.
Expert:  Appliance Guru replied 10 months ago.

SO the compressor or nothing runs correct?

Customer: replied 10 months ago.
Nothing runs. Interior lights come on.
Expert:  Appliance Guru replied 10 months ago.

Then you need to likely replace the temp control. Get at that and jumper the two wires to it together, if it comes on which it should replace that.

You're the expert but I thought we were going to do some tests with a volt meter.
Expert:  Appliance Guru replied 10 months ago.

First do that and then we can go from there ok?

Customer: replied 10 months ago.
Since there are 2 temp controls but only the fresh food side dials down to Off I assume that is the one I jump. The
Expert:  Appliance Guru replied 10 months ago.

Yes exactly

Customer: replied 10 months ago.
Since I am not a tech this is going to take some time. In order to access the freezer control I need to remove the light shield, console, knobs, extensions and the fresh food control first. It is already 9:30 my time. What hours are you available? I'm thinking about starting on this fresh in the morning.
Expert:  Appliance Guru replied 10 months ago.

Just post back to me I answer most of the day.

Customer: replied 10 months ago.
