Ice forms on copper pipe under freezer off compressor

Ice forms on pipe off compressor and small hot bullet like copper with coil wrapped around pipe is not sufficiently hot to keep the pipe dry and unfrozen (frigidaire upright freezer that's 2 years old). Initially it wasn't freezing so a handyman put freon in and broke ice located at the bottom inside and cleared the drain. Now I have the problem mentioned at the outset. APPRECIATE your help

    There is a large block of ice surrounding the coil that runs out of the compressor and up into the side of the freezer

It sound like your unit has a bad sensor on it or a leak. you should never have to add refrigerant to a unit unless theres a leak then it has to be repaired firdt the recharged.

Freezer insulation


Could you fit a trace heater inside the drain tube to keep the ice from forming? Or extend the dripdown time after defrost cycle so the water doesn't accumulate? If the tech thinks the insulation has blown, it may be time to bite the bullet and replace the fridge.

Hotpoint FZ175G red warning light comes on freezer still freezing after reset light comes on again after a couple of hours


Red light on for High Freezer Temperature Warning
or freezer not cooling, but fridge is and a lot of noise from compressor.
Also, fridge drain hole blocked, water in bottom of fridge.


This is a common fault in Hotpoint Fridge Freezers and can also happen if the door has been left open or has been a power cut.

1. Turn off fridge freezer, or at least turn down the freezer temp to minimum, though not ideal.
2. Open freezer door and remove all drawers.
3. Remove the back panel on the inside of the freezer. This is held in place with 4 screws, which might be 6mm hex head or star allen head. Pull the panel out.
4. Behind where the panel was, there is a cooling element for cooling, pipes, and below this a temperature sensor. If the fridge freezer is not switched off, then fold together a few layers of tinfoil and wrap around the sensor.
5. Use a hairdryer to slowly melt the ice. Melt it around areas where it appears to be hanging on, such as the corners of the cooling element or bolts, as well as any thin sections below the main block of ice around the cooling element, which will be supporting the main block. Use a plastic ice scraper to remove ice but not near pipes or sensor.
Warning: Be careful using electrics around water & melting ice & drips.
6. Below the cooling element, there is a drip channel & drain hole. If this hole is full of ice, pour a small amound of warm water down, leave for 10 seconds and pour a bit more until clear.
In the fridge, clear the drain hole in the same way.
Warning: Do not pour a lot of water down, as this water drains onto a tray above the hot compressor at the rear of the fridge freezer to be evaporated by the heat of the compressor and the tray will only hold a small amount.
7. When all ice is removed, dry all moisture. Put the shelves back. Close door. Turn on fridge freezer. Turn up the freezer temperature to your normal setting. Turn on fast freeze if available. After 1 hour, check with a thermometer. It should be cold enough after 1 or 2 hours.

I have a true 2 door freezer with bun rack rails...it is runninig between 7 degrees up to 59 degrees...we vacumed the vents...do we need more coolant or what do you think...it is about 4 years old and...


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.

Side of freezer seems warm


Hi!!

Don't worry about the line, it is supposed to be the way it is. If you are talking about the condenser coil, located on the back bottom part of the unit, with a small fan in front of it, yes, it is supposed to be hot.

The condenser job is to disipate the heat absorbed by the evaporator (the coil inside the freezer). Make sure the condenser is clean and condenser fan is working, also, make sure there is air circulating thru the back of the unit to help cooling the condenser.

The noises you hear, are probably the defrost coil melting the ice on the evaporator, this function is on a timer and happens 3 or 4 times a day.

Good Luck!!

Ice forming on copper pipe coming from compressor


Hi, It is not uncommon for the suction line on a unit to have ice on it when cooling. This means that where the ice starts forming on the line, there is liquid freon there. But, if it continues to get worse, would indicate a problem as you don't want liquid freon to enter the compressor as it will burn out the valves, or slug it as we say. Icing of this line can be from a few things. Low on freon will cause it to ice up. The freezer fan/evaporator fan motor not working. The freezer iced over real bad. An over charged system will do this, but you haven't had to charge it. Check the fan I mentioned and keep an eye on this line and monitor the units temperature. If you start to loose your cooling then we need to go from there. I can't prevent it from forming ice unless I was on site to install my service gauges to check the internal condition. Please keep me posted though. If the freezer fan is not running, this would be the problem and would need to be replaced. If you had excess to a volt meter and it wasn't running, you could check power to this motor. Let me know if it is not running and check the temperatures closely.
Good Luck,

Frost free freezer forming layer of clear ice on floor of freezer


This sounds like clogged drain / hose in the freezer compartment, here's why:

When the defrost circuit turns on, the compressor turns off. The defrost coil melts frost that collects on the freezer coil and drips in to a small pan located below the coil. The pan is formed so that the water that drips in it can flow to a hose connected under it. When the defrost cycle completes. the compressor runs again, bringing the temperature in the freezer to about 0 again. Any water remaining anywhere in the freezer will turn to ice very quickly.

If the hose should become clogged with ice, or slowed by mold, bacteria, etc. - water flow will be slowed, and / or eventually stopped. Ice will become thicker and thicker on the floor of the freezer as there is no place for the water to go.

A service manual for the appliance would be a good idea, but may not be required. You'll need to unplug the freezer and empty the contents. Defrost manually with a hair dryer or other heat source. If you decide to chip away ice, do so carefully.

The defrost and drain area of most refrigerator / freezers are located behind the rear panel of the freezer compartment. This is where the manual would indicate where the parts are located. Remove any ice maker installed if needed to remove the back panel.

Defrost any ice previously hidden by the panel. Chipping ice here should be a last resort, as sharp edges can damage cooling coils, tubing and the drip pan itself. Use a turkey baster filled with hot water to direct a stream at the area of the pan filled with ice. Hot water will likely have to be directed down the opening on the pan to melt ice in the hose as well.

Once the ice is cleared, mix about a 10% to 20% solution of bleach and water (1/2 ounce bleach to 3 ounces water) and direct down the drain hose. This will kill and inhibit further growth of mold and bacteria in the hose, which should help it drain water quickly.

Re-assemble and plug into power.

I hope you found this Very Helpful. If you need more help, ask again - but include the freezer manufacturer's name and model number. Good luck!

Very thick ice collects in bottom of freezer


the drain pipe you cleaned out has a p-trap that holds water. after awhile this trap will build up sludge and possibly freeze up. i recomend defrosting the drain pan again and try some way to forcfully flush hot water thru the drain. I use a turkey baster filled with water to do this. if the drain continues to freeze you may need to install a heat trap to keep drain from freezing.
a heat trap is just a piece of 10-12 guage solid copper wire with about 3 inches in the drain and the other end wrapped around the defrost heater which is the BLACK rod attached to the bottom of the evaporator coil in the freezer compartment. if you need any further assistance just let me know Peyton
