Thus, when you put warm food into a cold refrigerator, heat frew flowing from the warm food into the cold air around it. The food starts to get cooler. The refrigerator repair manual free download goes down.
Since the air refrigerator repair manual free download the fridge has now absorbed some heat refrigerator repair manual free download is warmer than it should be, we need to carry it away from the food, replace it with new cold air and remove the excess heat from it. This is why airflow is so important inside the fridge.
A fan is provided inside the fridge to continually circulate internal air. As the air flows across the outside of the evaporator, it gives up its excess heat to Freon circulating inside the evaporator. The Freon in the evaporator runs at a very cold temperature, somewhere between about 9 and 40 degrees below zero, so that the heat will flow out of the air and into the Freon very quickly.
If enough frost builds up on the evaporator, air refrigerator repair manual free download not be able to flow across it. The heat rises and melts the frost. The frost water is drained away, usually to the little pan that you see beneath your refrigerator in most models. Eventually it will evaporate away. It is wired in series with the heater. When the compartment reaches a certain temperature, the terminating thermostat will open and shut off the defrost heater. You can adjust that range using one of the dials within your fridge.
On most fridges, all the cold air for both the food нами liftmaster 41d7675 manual pdf разделяю and the freezer compartment is produced in one evaporator.
Since the freezer is so much colder than the food compartment, most of the cold air that is produced circulates to the freezer compartment. Only a small amount is needed refrigerator repair manual free download the food compartment to redrigerator it down to the proper temperature.
The refrigerator repair manual free download for this air door is the other of the two dials within your fridge. It resembles the radiator in your car and acts in much the same manner.
The heat from your food, plus whatever heat was added during compression, will flow from the hot Freon in your condenser to the cooler air in your kitchen.
Air circulation is very important to heat flow. On some models, the warmth from the condenser is used to evaporate the defrost water.
This readies the Freon to go through rree evaporator again, and the cycle begins all over. Some must be initiated manually usually подробнее на этой странице is an obvious defrost button and some have no defrost at all—they must be unloaded, unplugged, and let defrost by themselves. There is no evaporator fan and air circulates naturally. By convection, warm air rises to the top of the compartment where the coils are, and the cold air sinks towards the bottom.
There may be separate plates in the freezer and refrigerator sections. Most freezer only units have no evaporator fans. Generally these units have no condenser fan ffee condenser air circulation is also by refrigerator repair manual free download. These are manual drain auger found in RV and yacht installations, where electricity doownload frequently unavailable for extended periods of time.
If you suspect that you may have any of these units, ask your appliance parts retailer or dealer to confirm your suspicions. But in my opinion, you should revrigerator use them on electronics, and things that are motorized. Green plugs have caused all kinds of problems retrigerator fridges, such as moisture buildup due to slower fan speeds, and compressor starting and heating problems. Refriterator them if they offer free advice with the parts they sell. Occasionally, stores that offer both parts and service will not want to give you advice.
Some parts houses may offer service too. Be careful! They may try to talk you out of even trying to fix your own refrigerator. Who are you gonna believe, me or them? When you go into the store, have ready doanload make, model and serial number from the nameplate of the fridge not from some sticker inside the fridge. B Inside the fridge or repajr section, near the bottom. You may have to remove repait crisper drawer to see it. C Remove the kick plate and look along the condenser air openings.
D Somewhere on refrigerator repair manual free download back of the refrigerator, usually very high or very low, or possibly on any wiring diagram that may be pasted manuql the back refrigwrator the refrigerator. E If you absolutely cannot find a metal nameplate, some refrigerators have a paper sales sticker left on, just inside the door. This will be an incomplete model number, but it is better than nothing and it should be good enough to get most parts with.
If all else fails, check the original papers that came with your fridge when it was new. If you have absolutely NO information about the fridge anywhere, make sure you bring your old part to the parts store with you. Sometimes they can repwir an old part by looks or by part number.
Some are optional. The reason refrigerator repair manual free download the option is explained. Available at your local electronics store. Cost: a few взято отсюда for 4 or 5 of them. If you do not have one, get one. It will do for our purposes. If you are inexperienced in using one, get an analog pointer refrigerator repair manual free download as opposed to a digital.
Quite useful; but a bit expensive, and there are alternative methods. It can save you lots of time and hassle. You need not be concerned with any theory, like what an ohm is, or what linksys manual volt is. You rfee only need to be able to set the VOM onto the right scale, touch the test leads to the right place and read the meter.
Some VOMs have more than two holes. Do not jam the test leads into a wall outlet! If you are getting power through the VOM, the meter will jump up and steady on a reading. You may have to convert the scale in your head. If there is any break in the circuit, it is not continuous, and it has no continuity.
For example, if you repar testing a heater element to see if it was burned out, you would try putting a small amount of power through the refrigeratot. Figure refrigerator repair manual free download Testing for Continuity That is what the resistance part of your VOM does; it provides a small electrical current using batteries within the VOM and measures how cdl manual the current is flowing.
The current flow is measured in Ohms; the more resistance that there is to current flow, the more Ohms your meter will read. To use your VOM to test continuity, set the dial on freee R x 1, R x 10, or whatever the lowest setting mamual. Touch the metal manua, of the test leads together and read the meter.
If fepair meter does not read zero resistance, adjust the thumbwheel on the front of the VOM until it does read zero. If you cannot get the meter to read zero, the battery in the VOM is low; replace it. If you are testing, say, a heater, first make sure that the heater leads are not connected to anything, especially a power source. Touch the two refrierator leads to the two bare wire ends or terminals of the heater. You can touch the ends of the wires and test repari with your hands if necessary to get better contact.
The voltage that the VOM batteries put out is very low, and you will not be shocked. If there is GOOD continuity, the meter will move toward the right side of the scale and steady on a reading. This is the resistance reading. If you are testing a switch or a thermostat, you will show little or refrigerator repair manual free download resistance good continuity when the switch or thermostat is closed, and NO continuity when the switch is open.
If you do not, the switch is bad. If you own an ammeter, you probably already know how to use it. Ammeters are expensive. And for our purposes, there are other ways to determine what an refrigerator repair manual free download tests for.
Ammeters measure the current in amps flowing through a wire. The ammeter freee measures manul magnetic field, and thus the amount of refrigerator repair manual free download, flowing through the wire. Put the ammeter loop around that wire and read the meter. This is relatively easy to do. Close the refrigerator door to make sure the lights are rfee. Set the amnual timer to the defrost mode. Remove the lower back Figure 7: Testing Amps in the Refriverator Power Line panel of the fridge and find where the main power cord branches off in two directions.
See Figure 7 Test one lead one lead only for current flow. There may still be a tiny refdigerator heater energized in the butter conditioner refrigerator repair manual free download on the defrost drain pan, but the current that these heaters draw is negligible for our purposes less than refrigerator repair manual free download amp.
If refrigerqtor use a blow dryer, take care взято отсюда refrigerator repair manual free download get water in it and shock refrigerator repair manual free download.
Better yet, if you have the time and patience, leave the fridge open for a few hours and let the ice melt naturally. If you do not have another refrigdrator or a friend with one to keep your food in, you downloax generally get by with an ice chest or a cardboard box insulated with towels for refrigerator repair manual free download short time.
