GE Monogram Model ZISW42EMD Defrost indicator light

11 posts in this topic

Honorable Sensei, most humble student has problem with GE

Monogram Model ZISW42EMD

Complaint:  “de”

indicator light flashing on panel

Observations: Freezer and refrigerator sides felt cold

Next day “warm” indicator began flashing

Refrigerator side increased in temp-“it lost that cooling

feeling”

Observation: “This is a good excuse to get rid of husband’s

old ketchup, relish and salad dressings”

Troubleshooting steps:

1.  Turned off unit with inside control knob

2.  Cut power for 48 hours by unplugging the power connector above

the doors.

3.   Filled the dumpster with husband’s old condiments and

dry salami.

No water observed on floor after “defrost” means no frozen

coils?

4. Powered up and turned unit back on with switch

Everything okay, danced the happy dance around kitchen.

5.  Pressed

“status check”; tested ok with no faults

High fived husband and went to the store for beer!

 48 hrs later the “de” light came on and stayed on

 1.      

Cut power in order to reset

2.      

Taped down a (TBD) switch at top of freezer door in case the

switch was not making contact. Other switch is inside light.   Restored power, all okay did

happy dance a little more slowly.

 24 Hrs later  

“de” light comes on again.

 I am trying to troubleshoot this thing down to a level that

I can repair or know that the repairman is repairing the correct part and

restoring function.

Pull ice bin. Reach fingers up thru the square holes in top front of freezer compartment.  Does it feel frosty?  if yes goto A

A Pull the top service panel.  Rotate the timer slowly until the compressor stops. The timer is in the middle just above the doors.  It looks like you could stick a dime in there to turn it.  Mark the time.  Listen carefully for the sounds of your defrost heater melting and sizzling frost.  You should hear something within 10 minutes.  Your timer should advance out of defrost  within an hour of when you put it in. 

Report back with your observations.

With a mirror I could see that the inside was white sytrofoam and not frosty.  I did feel the back of the inside and it had a light layer of frost.   I have the top panel, the vented cover, removed.  I can see the cooling unit on the left and baffles on the right. There are only two metal boxes.  There is nothing in between.  With this model perhaps the timer is located in another area?Next recommendations or clarifications?Thanks!

    I could be wrong but the force is telling me that you might not have reached in far enough with your fingers to touch the coil.  You are describing a defrost problem.  Just because you haven't seen the frosted coil yet doesn't mean it doesn't exist.  If you have to you can take it apart far enough to pull the evaporator fan.  Don't take it apart any farther than that.  Use your mirror in the fan hole to see the evaporator coil..   Find the timer first.  Its mounted on the shiny sheet metal just to the left of the compressor.   GOTO A

even tho I do not know the way I will trust the Jedi Master and the force.  I will use my lucky screwdriver and the junior light saber, I call Mag, to move farther into the dark space.

I think we fixed it!  I kept looking for the timer and found it hidden behind insulation, wires and sheet metal.  Long story short is we ordered the part  though the Samurai's link to give them credit and installed it yesterday.  All alarm indicator lights off and both sides are cold.  Thank you !AJ

   I'm glad you got it working.  What convinced you the timer was bad and were you able to hear the sounds of the defrost heater?

As I was following your directions and letting the force guide me I felt the presence of the dark side near.  I surrendered to it and my husband took the screwdriver from me.  The the dark side is very strong and I am weak under its power.He took apart the timer and decided that the resistor was bad because it tested so with the meter.   We decided not to try and replace the timer at the resistor level, because we could not find the correct level, and the we had to buy a new one now that the other one was in pieces.I could not ever hear the defrost sounds, I did not see frost build up like I would have expected to if the heater was not working.  We thought that to start replacing the timer made since.  It has been working for several days now with no indicators registering.Any other suggestions?Thanks,
