Question about Refrigerators
Fridge freezing up- and no fan or air circulation:
The fan usually stops working due to ice obstruction when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature.
May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..
Another item to check with a meter is the heating element itself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS .
Lastly check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?

SOURCE: I've got an electrolux frost
remove the back panel inside the freezer and check for ice build up on the evaporator pipework. if ice build up, this prevents air flow and hence temp rises.
remove ice carefully with a hair dryer and it should work. if problem comes back, you have a problem with the defrost system and get back to me if you want

Check the compressor with a volt meter, if the compressor is getting proper voltage then check the relay. But this sounds like a problem with the compressor

the thermostat has broken down and needs to be replaced,, normaly when they brake down they just stay in the closed poshion so the fridge freezes up get a new one fitted and all will be well

Testimonial: "Thanks for you fast response, very helpful. I thought this may be the problem but wasnt sure. Are the thermostats easy to replace? Could I DIY, How?"
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

Testimonial: "Thanks, I have checked that, but the vent at the bottom of the fridge section is a rigid plastic grill, which doesn't, nor looks like it should move. "
