Question about Microwave Ovens

1 Answer

We have a Teka fridge freezer A-FC1350. The fridge thermostat doesn't work though i have replaced it. We have opened the doors and left f/f switched off for 2 days, and i have looked at the control panel, which seems ok. What else apart from a component on the control panel could be wrong?

    Hi, can i replace the power relay easilyand how much is it? Looking at the board, it should be easy enough to replace as long as it doesn't cost as much as a new fridge!

Nothing - the defect is definitely in the control control board: either the power relay or the processor have failed. If it's the relay then it can be replaced by itself with a similar one that can be ordered here

If it's the processor then the entire board will have to be replaced - you will have to call the repair shop of a dealer, they are the only ones with access to spare boards.

    The relay itself costs about $10 and it's soldered in there - it has 4 feet: 2 for the command and 2 for the power to the compressor. To check it you measure the voltage across them: on the command side there should be 12 volts DC (it there isn't then the relay is not commanded and that is caused by a failure of the processor); on the power side there should be 0 (if you get 220 volts AC or more then the relay is not working). To replace it you just desolder its feet and it pops out - beware, its plastic case deforms very easily from heat, do not overdo-it on the feet

The freezer part is working fine ,it seems as tho the refrigerator part is warming instead of cooling


The freezer is actually where the cold originates and is passed through into the refridgerated area.
Open the fridge doors and check that the air passage is not blocked by something stored against it. It's probably on the top shelf and looks like a louvre vent. There may be another down by the crisper drawer

FRIDGE button is set on 3, red light flashes, air system works but it is not cool for at least 1 hour, Freezer set on 4 S and works.


Start out with the easy stuff first...make sure the lights go out when you close the door(s), make sure the doors are closing properly and the gaskets are closing fully and not torn. Check to make sure the evaporator fan in the freezer is working, this fan blows the cold air around. If the fan is not working, possible bad fan motor - check for power to the fan motor and also check the fan switches around the door openings, ( if your fridge has these switches, not all do ). A common problem cropping up in the last several years has been the air damper not opening up and allowing the cold air from the freezer to be blown into the fresh food section ( mostly on SxS refrigerators ). For many years the air damper was manually operated and now we have motorized controlled or temperature controlled or thermistor and electronic boards controlling air dampers, and if this device sticks closed the FF section will normally warm up. An example picture of "one" style and an air damper ( called a diffuser by Whirlpool ). Next would be to check the condenser tubing, a good place to start is to make sure the condenser coils are not built up with dust!! Make sure the condenser fan motor is also working properly. Check for any "clicking on and off" noises from the compressor, is the compressor running.
The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some behind the cold control cover. Once you locate the defrost timer, slowly turn the screw like wheel in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can ohm test the defrost heater for continuity or volt test for 120 volts to the heater(s). If you have no power to the defrost heater(s) you can also bypass the defrost thermostat to see if the defrost heater will come on, join the 2 wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it. Then make sure all the vents are clear and not being blocked by food cartons. One new safety device added to refrigerators in the last few years has been a in-line fuse added to both sides of the defrost heater. If one of these fuses let's go, you must replace the whole defrost heater, as it comes as an assembly. If the defrost heater does not work, you should check for one of these fuses being open. Check it with a volt meter or ohm meter.
New link from Appliance Repair Aid on how the wiring circuit works for a frost free fridge, the link is here.
On a frost free refrigerator, the cooling coils should be in the freezer section. On a SxS style refrigerator the coils will be behind a cover on the back wall. On a freezer on top style the coils could be behind the back wall or under the freezer floor. Removing the cover and exposing the evaporator coils could be a valuable tool. Seeing what the cooling coils looks like may help split your not cooling problem. Totally covered coils with white snow is a frost free problem. and the rest are bare is an indication of a system problem

Sub zero 532 fridge is not cooling porperly but freezer is fine


Top of Form

If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

Freezer works but frig not cooling


if you were to reach your hand towards the rear inside the fridge area can you feel cold air blowing into the refrigerator side if not this could either be due to the fan inside the freezer area not working or there is a small door that is controled by a thermostat inside the ceiling of your refrigerator this thermostat when it reaches a tempreture that is to warm it opens a small door in the rear that connects to the freezer allowing cold air to come into the refrigerator side when the refrigerator becomes cold enough the thermostat then shuts the door. You could also have a defrost issue inside the freezer area in which u would need to remove the rear panel in the rear of the freezer in order to assure you did not have this issue. If you remove the rear panel and you see any ice build up on the evaporator coil (note this is also where the fan that blows the cold air into your refrigerator is located)you would have a defrost issue. If you remove that rear panel and find any ice build up message me back and il instruct how to fix but first check to assure you have air blowing into the refrigerator side. If you dont then you have to diagnose which is causing the issue either the fan which you could hear if you listened inside of the freezer area or the door itself is not opening due to a malfunction with the thermostat if you have any further questions message me back and please also remember when our chat has fully conlcuded to rank how this opinion has helped it allows me to continue helping others in similar situations Thanks

SMEG FA550X fridge freezer. The ice maker has stopped working, freezer has thick ice built up at bottom, fridge does not appear to be keeping food cold enough as milk etc is going off quickly. Two to...


Your Ice maker may be the cause. if it is not holding water the water may be landing on the bottom and freezing, causing the ice build up and obstructing the air transfer from the freezer to the refrigerator. You can remove or replace your Ice maker. Then you will have to defrost your freezer to get everything back to normal.

I have a Teka A-FCI340 fridge/freezer. The fridge is too cold and freezes items put into it. No matter how I turn the temperature control dial it still seems to be too cold.


I had the exact same problem with the same model and mine was just 3 years old. My problems started when I defrosted the freezer. I spent 75gbp on an engineer who told me that I had probably 'spooked' the fridge when I defrosted the freezer, that this particular model of fridge wasn't designed to last longer than 2 years.

I would recommend you check the door is shutting properly (check the screws at the top, it might be just slightly out of alignment).... I turned the whole unit off for over 2 days to allow absolutely everything to defrost (both inside and on the back of it)... within 30 minutes of turning it on, the back of my fridge was already frosted over.

Engineer told me not to waste money calling them out again, and to buy another one...

My freezer is working but the rest of the fridge is hot


Hi, it is possible for your freezer to work when you fridge is not working. Fridge-freezer appliances have independent controls which can malfunction separately. If your freezer is fine and your fridge seems down, there are several things that could be wrong but what i suspect is that... You should check the damper door located between the freezer and fridge compartments to make sure it opens and closes, sometimes they get an ice build up there and this causes them to stick shut, remove ice with hair dryer or remove and device and replace this will solve your trouble.
Best of all is to call in a local fridge technician around to get it fixed, it won't cost you much...

Take care
