Question about Hotpoint FFA70 Bottom Freezer Refrigerator
Red light has been on for a few weeks yesterday it just defrosted the freezer, red light is still on but the freezer is not working.
SOURCE: High temp red light stays on...
You'll need to tear into it to answer these questions. I suspect the defrost cycle isn't working or the fan is broken. The best way to see what's going on is to take everything out the freezer drawer and remove it. Then take the back panel off the interior rear wall of the freezer section to expose the coils. The coils should have a very even white frost pattern on them (not frozen solid anywhere). If they are frozen up then the air can't flow around them to cool the fridge properly. If the coils seem "normal" with frost only then is the fan just above them working? That fan circulates cold air to both fridge and freezer sections. Let me know what you find out in order to lead you to a repair part.

sum fans only kick on if cold enough
if the whole evap is frosted up u have a defrost problem
if frost is only partial u need to throw it out cause it either has a bad compressor or freon leak
check your fan by compressor and make sure coil isnt filthy too

You will need to remove the bottom freezer crisper and check the defrost drain , to see if it is iced over . If so , then use a hairdryer to melt the ice ( hot water also helps ) . When you see the drain , ( could be obvious obstruction from plastic ) , use a small hose inserted into the hole , to blow thru , to remove any unseen debris blockage .
You may have to remove the rear inside freezer panel to access this drain , depending on your model number . So make sure the drainhole is open. When it happened to mine this was the problem.

SOURCE: Freezer temp. goes high
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.
If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.
If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.
The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.
If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. 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 because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.
If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and the back in others.
