I have GE refrigerator model ZIS42CMC. The evaportor coil is icing up. The defrost heater shows no continuity. In order to replace the defrost heater element I have removed the refrigeration unit from top of the refrigerator, removed the evaportor fan, disconnected the thermostats, disconnected drain trough heater, disconnected defrost heater and removed the drain line from the evaportor coil compartment. How do I remove the evaportor coil from the evaportor compartment so that I can access the defrost heater for replacement?
You don't as to do that will loose all the gas and you will be in a bigger cost zone than having a technician fix it

If the freezer is on top then empty out the freezer and remove the bottom and back liner of the freezer compartment usually phillips screws. In the back you will see the freezer coils along with a defrost element. Below these two items u will see a drip tray that collects water from the coils on defrost cycle, in the center of the pan will be a drain hole that connects to a hose that leads to a pan under the refrigerator.Normally the water is collected there and evaporated. The hole in the tray in the freezer is clogged. Thaw it and clean it until you can pour water in it and it goes to the pan down below. please rate me
algae, bread ties andf other thing mysteriously get in there and clogg it

Check for a blockage around the through area from the freezer to the refrig. or something such as a jug of milk that you keep in the same loacation time after time. if this jug or what ever stays in this area that can cause a cold spot and keep that area from getting warm enough to let ice thaw.
SOURCE: My GE fridge is not defrosting the coils in the back. What's up?
if u have frost build up in the freezer it will affect the temperature
and it needs to defrost
problems could be
defrost timer.
thermostat.
terminator.
heater s.
unit problems (unlikely) if even frost coating.
SOURCE: GE Monogram Built-in refrig has blocked evaporator drain.
You should be able to see the drain under the coil. Part 804 on this diagram. Your drain tube may be stopped up with ice at the upper end
because it drains too slow because it's stopped up at the lower end in the
evaporator pan under the unit at the floor. It can get dust and mold in it.
Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing
it out with hot water and clorox may help.
Make sure it drains quick enough
to prevent refreezing.

My Haier wasn't defrosting right, ice would build up & the freezer would be fine but the fridge temp not right. After reading lots of posts, defrosting a few times,etc., I took advice & ordered a new defrost timer. (Repair Clinic) They had diagrams that showed where things are. This is everything I did. Unplugged it, cleaned off everything in back, double checked fans were all working, drain pan draining, in freezer took off panels to make sure ALL ice buildup was melted including drain hole. Made sure everything was connected (there is sensor w/clip that could be near or on the condensor coils & it wasn't on - so I made sure it was on) - dried things, put back together. Changed the defrost timer. Plugged back in. Two weeks have gone by and things are just fine! You definitely need to completely defrost the fridge because even if the defrost timer is the problem all the ice built up won't allow the fridge to defrost in the defrost cycle. You'll want a fresh start & it's worth it! I thought we were going to have to buy a new fridge! And my husband is proud that I did the trouble-shooting & repair all by myself! Thanks to all the help I found online!
