Avanti FF1008 frig not working.no cold in tubes to condenser in freezer. See photo If it helps, note frost on small tube coming out of copper cylinder. timer,heater,compressor seem ok.

The hose coming from the bottom of the freezer is draining the melted water produced during the automatic defrost cycle. Usually the water is collected in a pan somewhere around the hot compressor motor so the heat can evaporate the water.

The hot copper tube by the compressor is the high pressure tube going to the condenser. The other tube going to the compressor is the return line from the evaporator and, after normal operation, is cold to the touch. It is this cold refrigerant returning to the compressor that cools the motor.

Hello,

Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze - store them in a different spot. Doors not closing properly making the fridge run too long is something else to check for.
Also check the plastic air deflector at the top rear of the frig had been knocked off. As you know, the deflector directs the freezer air toward the front of the frig and the rear of the cold control,

Hoping this will help in solving the problem....

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


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. . The drain should be located below the evaporator coils on the lower back of the freezer.

Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer. If this repeatedly happens with yours, you may can prevent it by taking a bare copper wire and wrap it around a fin near the heater and put the other end a few inches down the drain. The heat convection may prevent it from freezing.

Is the compressor motor running.If no check starter/overload relay.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm

Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

I just worked on a FF801W which is supposed to be very similar. The defrost heater in mine was of the glass tube type and located under the evaporator. There was a bimetal thermostat clipped to the top of the evaporator and a thermal fuse (sealed in a clear plastic tube) nearby. The connections were behind a little plastic cover (2 screws) in the back wall just above the evaporator.

Mine was iced up like yours and I had to defrost it with a hair dryer. All the defrosting parts in the freezer compartment turned out to work so I now suspect the defrost timer (down by the compressor). I've marked it and I'm waiting to see if it's turning.

just about all friges work off the frezer .the evap fan moves the air fromthe frezer to the frig.so you would here fan noise.i dont know your brand but on most frezers if you turn the frezer temp to the highest setting thats acomplished by keeping the air from going to the frige.hence warmer frig temps .also make sure fan on out side back is working and condenser is clean.again turn air damper control from frezer to frige to lowest setting .somthimes this could be in frig section.God bless ,tom

Hi. thanks for the question. the reason the ice builds up at the coil, at the back . Is because the fridge, is running way too long..If # 1 is where you set the fridge . replace the thermostat, This will solve your problem .Thanks the appliance doc

give the unit a full defrost then unblock the drain hole. it sounds like the tiny defrost heater element may not be working and is therefore causing excess frost to build up on the freezer evaporator. also check door seals are not holled anywhere.
