Have a ac specialist check the charge pressure in the system
I suspect that the refrigerant gas amount is not correct and the problem is that the pressures sensors are causing it to cycle according to the fluctating pressures

What is the probable cause if the compressor operates in on/off situation....already check the blower but still compressor stops for a minute


It may be turning on and off in the cooling mode either due to a "low freon" charge. Can you tell if the condenser fan motor is running? The compressor may also shut off if you have too high of "head pressure"

Why does my A/C condenser compressor turn on and off every 5 minutes?


You need good airflow across the indoor coil, the evaporator. Air warms the refrigerant. If there is no airflow, the refrigerant will come back out freezing cold (in liquid form) and can damage the compressor valves. Before charging any ac unit, good airflow must be checked for across both evaporator and condensor.
Too much, overcharging will cause freezing all the way back to the compressor in a capilary tube type of ac.
Where is it the refrigeration lines are freezing cold?

Suction line has leak do i have to take freon out to repair


yes . If you don't the heat from the torch will make the freon increase in pressure so the silver solder will never flow into the joint. The worst thing you can do is put an open flame on a freon leak. It produces fosgene gas which is deadly.

The unit will not cool below 78 degrees. How do I check the freon level?


Without refrigeration gauges, you can't check your freon level. You have to check the pressure of the freon, not the level. If you are careful and have a basic knowledge of electricity and moving parts, you can get an idea if you are out of freon. If you remove the lower slotted cover from the refrigerator you will see the condensor coils. This is a radiator that has aluminum fins on the front and will have a fan running behind it. If the compressor is running this condenser coil should be hot to the touch at the top part of the aluminum fins. If the fins are covered with dust and dirt it can cause your cooler to malfunction. Also if the fan is not running the compressor will overheat and quit. If you pull the cooler away from the wall, you can see the compressor in the bottom of the cooler. There are two copper lines leading to the compressor. The small line goes to the condensor coils (the radiator) and should be hot enough to burn your finger if you have enough freon. Also the larger of the two copper lines brings the freon back to the compressor from inside the cooler. It should be cold to the touch if you have proper freon pressure. If both of those two lines feel about the same temperature, either the compressor is not running or you have no freon. BE CAREFUL! There are electrical lines and moving fan blades near the compressor, and some of the tubing gets really hot.

For my thesis: 5 condenser problems and 5 solutions


Problem number one.

condenser fan won't come on. solution check the capacitor if good ohm out the fan to see if it is bad. If bad replace fan motor with new one.

2. compressor will not come on. solution check the contactor to see if engaging this applies to problem 1 also. If engages check the capacitor on the herm side if it is bad replace. If good check compressor to see if the compressor is bad. Should it be bad replace compressor.

3. High head pressure not cooling properly dirty condenser coils. Clean coils. With hose and water.

4. Low head pressure frosting accruing on suction line. Check freon levels. Also check inside air filter for being dirty.

5. Condenser unit is failing to come on. solution check the power source check the contactor should the main power be bad check main breaker and replace any slow blow fuses that are bad. Should the contactor be bad check transformer to ensure 24 volts going to secondary side on contactor. Inspect the two wire going to outside unit condenser. replace any broken wire any bad transformer or bad contactor.

Fridge/freezer not working but light is on,located in garage,which iss v cold

Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm

Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

Not all refrigerators are insulated the same and not all condensers are in the same place. Your cold control is monitoring the temperature of the refrigerator section and is designed to turn off the compressor to keep things from freezing in that section. If it stays cold long enough outside in your garage the cold control thinks its cold enough and won't turn the compressor on. A makeshift closet to hold a little heat the unit generates will probably help.

evaporator coils are behind the rear cover inside the freezer at the bottom.

Compressor or freon problem will require a repairman.

Sat in storage for 4 months. Now icemaker not making ice and frig is not cold enough to keep milk from souring.Your ideas? Whirlpool Refrigerator model: ED5JHEXTQ00


Check condenser fan that it is turning. Also it is possible you lost freon (leak) when it was moved. Take back cover off to see if fan is turning. Feel compressor to see if it's too hot indicating it lost freon,also feel the larger copper tube going into the compressor ,it sould be cold and sweating.
