What is a clixon

I feel for ya but nothing you can do besides report the first technician to the BBB and hire another, more reputible one

Could be a number of things. It has a thermistor that sits on the evaporator to keep the fan off until it gets cold. It also has a switch above the door that switches the fan on when the door's closed. It could be a loose connection in the wiring, or, lastly, it could be a seized fan

Give the evaporator a chance to get cold, then check you've got power to the fan, via the evaporator thermistor and door switch

Hi,

Let's start by diagnosing the freezer;

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food

As for the fridge, the same solution but for more details. If refrigerator is not cooling properly can be due to a defrost timer, which is causing the fridge to go into defrost cycle. Usually it takes 45-60 minutes for refrigerator to come out of defrost cycle. If the timer goes bad then it will not come out of defrost cycle and can result in this kind of issues. It can also occur due to defrost thermostat, it allows current to pass through it at temperatures of 20 to 30 degrees Fahrenheit and prevents current from passing through it at 40 to 60 degrees. This is difficult to test, though, because it takes a prolonged, very-cold temperature to turn it on. The defrost thermostat is snapped onto the top portion of the evaporator. The thermostat sends temperature information to the processor. The defrost heater must be replaced when replacing the thermostat.

1. Remove the lower fan duct work from the evaporator cover.
2. Remove the 1/4-in. evaporator cover screws and remove the evaporator cover.
3. Disconnect the defrost thermostat wiring connector.
4. Remove the defrost thermostat from the evaporator.

I hope the above helps.......

Regards.

If you have just turned it on it takes awhile for the fans to come on. The evaporator coil has to get cold about (10 to 20 degrees) and make a klixion fan switch to turn the fans ON.... Is the evaporator coils getting a frost pattern on them??? If not then the system may be low of Freon.. If the coil is completely froze up and you are getting frost back to the compressor..... then you have a bad fan switch or a door switch.... If you have a wiring diagram you can trace out the wiring.... It is usually down by the compressor or control panel... hope this helps.

Get to the compressor and feel its temperature. If it is cold, then the thermostat will be faulty. Not impossible, but the clixon and run relay inside the electrical box could also be faulty. One needs a digital tester to check both.

ok well... those pipes coming from your compressor one of them should be hot. if not your compressor is not running.

There are three main reasons the fans would not come on.
1: A bad door switch. There are switches on the top part of door frame. They turn fans off when door is opened to prevent warm air from being drawn into unit when door is open. If a switch goes bad the fans will never turn on.
2: Refrigeration problem. The fans are tied into a temperature switch called a fan delay. The fans will not come on until the coil is well below freezing. This is to prevent water spray after a defrost. If unit is low on gas or has any other cooling issue the fans will not come on.
3: Bad fan delay switch. If the fan delay switch becomes "stuck open" the fans will not be energized.

Feel the back of your evaporator coil, if it is very cold and frosted you probably have a bad fan switch, or a bad door switch. ;)

The fans are controlled with a clixon that has a cut in at 5 degrees, and cut out at 20 degrees. If the unit is running and the fans are not comng on then I would have to say you are out of freon. But your condensor fan could be running and the compressor NOT be running which could be a problem with your compressor. Find out if your compressor is running by taking an amp draw. If compressor IS running then you are low on freon. If the compressor is running and your evaporator coil is cold and your fans AREN'T coming on then your clixon is bad.

This sounds like a refrigeration problem. On most freezers there are temperature switches that control the interior fan and light. The fan and light will not come on until the temp switch senses that the evaporator coil is at freezing or below. The "h" is a "high temp warning I would gues. :)
