Vacuuming the coil is not usually sufficient to clean them properly. Hold a flashlight behind the radiator on top of the freezer to see if you can see freely through the coils. If not, the best way to clean the coil is to spray coil cleaner on there and flush with plenty of water. It is a mess but it will get the grease off the coild. If you do not have gauges to check the pressures of the refrigerant (lets call it freon), you can get a good guess by doing the following: Get a ladder, climb up so you can see in the top of the cabinet where the compressor is located. It looks kind of like a bowling ball. There will be one small copper line and one large copper line running from the compressor. The small line is the high pressure line. It should be hot enough to burn your finger. It then goes through a small pan where it evaporates excess water, then to a "radiator" which has a fan running behind it. If the machine is running this fan should be on. The small line then runs into the freezer box. At this point the line should be warm, not hot to the touch. If this is not happening you are probably low on freon. The other copper line on the compressor is returning from the freezer box to the compressor. It should be very cold to the touch. It should have moisture collection on it. If this is not happening you are probably low on freon. Other factors can effect your freezer. Make sure the fan near the compressor is running. Make sure the fan or fans inside the freezer are running. They will stop running when you open the door, so hold the door button in when you check the inside fans. Check also to see if there is a build up of ice on the inside coil. Your freezer should run a defrost cycle 4 times a day to remove the ice. If it has ice it will not run properly. If you can remove your product for 24 hours and shut the freezer down, prop the door open and the ice will melt. On restart if the freezer goes down to 0 quickly (30 minutes) it was probably frozen over. This may indicate a bad defrost timer or heater. Try these things.

Frezzer keeps icein over


Hello;

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

There are several things to check:

1.) Door Gasket -Take a piece of paper. With the freezer door closed run the paper around the gasket. If you can do that, then you are not getting a good seal.
Repair: Clean the freezer door gasket with soap and water. While still wet, take a hair dryer and a spatula, going around the gasket, heat the gasket while pulling the gasket out to expand it.
Note: This only solves the problem if there is frost in the front area of your freezer.

2.) Freezer fan not working - In some cases, The freezer fan helps to prevent warm air from getting into the freezer.

3.) Food Storage - Make sure you do not overload the freezer, and that the food product is inside the bounds of the racks.

4.) Fresh Food Section Air Vent Wide Open - This is your probable cause: Heat goes to Cold like a magnet. When you open your fresh food section door and then close it you are forcing warm air up the vent that goes to the freezer. You probably have a broken air vent assembly.

Ambient temperature


This is true of all HVAC type systems. The condensor releases heat from the expansion of the coolant. As long as the temperature is lower than the exchanged heat then there is no impact to efficiency.

True T-49 refrigerator/freezer temperature calibration


Contact the manufacture, it is most likely going to be covered under warranty. If the knob is not removable, (check for a set screw on the side of the knob it will take a small allen wrench) Then the thermostat (temp controller) will need to be replaced, if it isn't a style that you can calibrate.

Be sure the condenser coil is real clean. Best place to start. Freon levels, door seals are another place to look.

Normal Operating pressure for true 2 door Freezer R404A Room Under 80 degrees F Box at -10 degrees F


The pressures depend, somewhat, on the expansion device,i.e. a TXV or Cap Tube. Take a pressure reading, then convert it to a temperature. The evap temp should be right at 10 colder than the box temp. Remember, heat flows to cold so the evap has to "Lead the Load" in order to cool. In many cases, the condensing pressure is usually ambient temp, plus 30, then convert to a pressure. These are general accepted practices that have been used for many years.

Hope this helps
