Question about True GDM-33-SSL-54 Refrigerator

There is snow on the coil at the top, unit only cools to 48*. I have defrosted the unit and reset the dial to 1 as recommended in manual. Still hearing the clanging of either water or snow/ice hitting the fan. the drain pan underneath the unit is empty and dry. I can not tell if the drain line is clogged .

The drain line is mostly likely clogged.

You need to find the drain line and try snaking the line out with either compressed air or a fairly sturdy length of wire.

Taking the face of the evaporator fan off would probably help with finding the drain. Unplug the fridge while doing this so you arent working around live fans or the defroster!

Good luck and be careful.

Superba 48 stopped completely

Hello Shawn;

My name is Peter. I am a retired field service refrigeration technician.

You did not provide a model number. The model number is on a label, on the liner inside wall of your fresh food section near the top.

I picked a Superba 48 model number at random to see what you have. The model I picked - the control boards are not available. But these are not your problem.

Every 8-10 hours your unit completely shuts down except for the lights, and goes into a defrost mode. This is where your defrost heater turns on for 20-30 minutes, defrost your cooling (Evaporator) coil, and then turns your unit back on. You may have a bad defrost timer.

1.) Defrost Timer - Behind your unit is a defrost timer.



The timer is mounted on the back a steel bracket with a hole through it. Take a flat head screw driver, turn the round shaft one click at a time clockwise until the unit turns on and is running.
If the unit turns on, then you have a bad defrost timer.
Note: When replacing note what contact number the black wire is connect.

2.) Power On/Off Switch - In the lower back, you also have a Power On/Off switch. Unplug the unit disconnect the 2 wire leads on the switch. Using a multi-meter, set ant the lowest Ohms (Omega Symbol), Ohm out the switch. If you get a reading other that '0', then the switch is bad.

Refrigerator stopped cooling. As close as I can tell the fan in the freezer part was frosted up for a length of time and has possibly ruined the fridges cooling fan? Kenmore model 106 freezer on top.

If the fan in the freezer stops, then coll air from freezer will not pass from freezer section to fridge section.In that case, the freezer section will get over frosted but fridge section will not get cold, because cool air will not pass from freezer to fridge.The fan is there for two things, 1) for cooling the heating evaporator coil and 2) For flowing the cool air from freezer to fridge.---------- If the frost is getting collected and fan is getting stuck up in frost, then this is the problem.The defrost cycle is not running, the cooling cycle is running.---------------
This problem is called defrost problem.-------------

So first thing you try is , perform, manual defrost reset procedure.---------

The manual defrost reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. Then check,if same frost is getting collected, then its defrost problem,. If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. You can get required parts from from online sites like: --- or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some behind the cold control cover. Once you locate the defrost timer, slowly turn the screw like wheel in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can ohm test the defrost heater for continuity or volt test for 120 volts to the heater(s). If you have no power to the defrost heater(s) you can also bypass the defrost thermostat to see if the defrost heater will come on, join the 2 wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.
*One new safety device added to refrigerators in the last few years has been a in-line fuse added to both sides of the defrost heater. If one of these fuses let's go, you must replace the whole defrost heater, as it comes as an assembly. If the defrost heater does not work, you should check for one of these fuses being open. Check it with a volt meter or ohm meter.

On a frost free refrigerator, the cooling coils should be in the freezer section. On a Side x Side style refrigerator the coils will be behind a cover on the back wall. On a freezer on top style the coils could be behind the back wall or under the freezer floor. Removing the cover and exposing the evaporator coils could be a valuable tool. Seeing what the cooling coils looks like may help split your not cooling problem. Totally covered coils with white snow is a frost free problem. and the rest are bare is an indication of a system problem. System problems may be a leak in the refrigeration tubing,or an inefficient not 100% pumping compressor.

Sorry to hear about your problem. Sounds like you have a defrost issue. Hence your unit is not defrosting. All of this apply's if your freezer side has ice or is cold . If not. you have other issues, this does sound funny, but this is why your refrigerator side is warm, or not cooling.

Here is a list of some things that can go wrong.
1. Defective heat coil
2. Defective defrost timer
3. Defective defrost sensor
4. Defective Fan
5. Defective compartment inlet damper (on some models)

You should call a service company to resolve your issue.

Good day,
If the machine has been running at least 6 hours in cooling mode, and the thermostat shows open. It is defective, and needs replaced.

The evaporator fan should run all the time that the unit is out of defrost. The only time this fan is off is when the unit is in defrost.There are two pssibilities for the "snow", it is either the defrost timer or the defrost termination control. Change the defrost timer first, on 90% this is the problem. If not change the defrost termination control located on the refrigerant line leaving the evaporator coil.

Temp control on high food not freezing

Look for snowy frost build up on the inside rear freezer panel. If there is snow, your self defrost system is not working. 90% chance your defrost heaters are burned out (will sow open with multimeter set for continuity, Rx10, Rx100, etc...) If the heater is good check the defrost termination thermostat at the top of the evaporator (cooling coil) it is clipped to the top. About the size of 15 quarters stacked up.. two wires coming out of it. It will only show closed if it is below around 20 degrees. If neither of them is bad, replace the defrost timer. It is in the top of the fresh food section by the control dials.
