High temp light on, loss of door suction, ice in channels in back pannel of freezer, Why is autofefrost not working? Have to leave empty for 2-3 days to defrost.

the warming up will be because the unit is not operational and the door hasn't been opened
call a service technician and check for a failed start/run capacitor for the compressor
the high temp alarm indicates that the food is in danger of spoiling

Cold air sinks. If evaporator temp is not low enough only the items on bottom of freezer will get cold and possibly freeze - stuff on top will not.
Throw a digital thermometer in there towards the top shelves and I bet your temps are high. Low refrigerant will cause this; furthermore, if you leave the refrigerator door open by accident, the refrigerator will never shut off, the freezer evaporator will freeze over with a block of ice, and the freezer temps will be higher. If that is what happened, simply unplug the unit and allow it to self defrost and then turn it back on for proper operation and make sure that the refrigerator door is properly closed!

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.

if the temp. in the refrigerator side is 20f, its to low, set the ref. to 40f and freezer to 0f.

this can be multiple issues. look for the freezer being level. look for any missing screws where water can leak out during defrost. make sure the door closes and seals. be sure you have the right amount of defrost cycles at the correct length. check to see if defrost heaters work. you may need to add a heater to the drain if there isn't one. worst case: remove product overnight and store in another freezer, unplug unit and leave door open to defrost, then plug in first thing in the morning.

The air in the freezer is circulated by a fan, there are a number of possibilities
1. Is the internal fan running, this may be switched by the door opening, to test push the small switch on the door frame ( if fitted). If the fan is running go to
2. If the fan is running can you feel air coming out of the bottom of the duct inside at the bottom.
3. If there is no air coming out of the duct the duct is possibly blocked with ice, or the cooling coil at the top is iced up.
4. If there is no air flow then the best and quickest option is to empty the freezer, store your goods elsewhere, switch it off, use a wedge to keep the door partly open and leave off for at least 24 hours. You may find a large pool of water on the floor after this and you will also need to dry out the inside of the cabinet.

Icing of this type is caused by
1. Door not being closed properly, door misaligned or faulty door seals.
2. Putting "hot" product (over 2deg C / 34 deg f) into the freezer.
3. Not covering or sealing product being stored in the freezer.
4. Defrost timing not working (ask your service guy) for this and the rest I'm afraid
5. Defrost heater not working
6. Blocked condensate drain
7. Faulty thermostat, keeps on cooling

Hope this helps

I would check the thermostat, and check for loss of gas.

Things you can do to cut down on frost.
1.make sure all seals fit flush to frame.
2.use a thermometer and set freezer to -18c(beef will keep upto 12months).
3.wrap all food as airtight as poss.
3.do not overfill,leave space for air flow through drawers/shelves.
4.defrost every 2/3 months in humid conditions using clorine bleach to clean interior,and dry thoroughly.(leave door open to dissipate clorine gas.)

Hey there. First question I have is if you have a heat pump or straight ac. Straight ac is easy to diagnose. Your suction pressure will be high, your head pressure will be lower, not sure how clean your condenser coils are so its hard to say how high. Your amp draw on your compressor will be lower than normal. Also, when looking at the suction pressures, you have to keep in mind what temp the air hitting the evap coil is. If it is warm, that will make your suction pressure go up. Another way to check the vavles is to hold the suction line at the compressor when you shut it off. If the temp goes up the second you shut it off, this tells you the hot gas is leaking through your suction valves. You can also try to pump the system down, then shut it off and see how fast the pressure builds back up, this will give you and idea how fast it is leaking through. Let me know if you need any thing else, I'll be here.
