I have a freon leak. it is leaking where the line goes it the unit under the house. the main line then looks like it branches off into 3 or 4 very small lines and then goes into what looks like a radater.

Hello, if the pressure is dropping that fast there is a leak on the low side, mighr be a schraeder valve or possibly around compressor. However whn charging freon both valves should be open or the freon will pump down in the condenser and the low side pressure will drop to 0

more than likelo low freon, and yes their are 2 seals that can leak under the hose manifold

Sounds like you have a good sized leak in the system. The service man should be able to locate a leak that big. You might be able to locate it yourself. It's more than likely in the outside unit or indoor coil not in the lines that run between them. Look in the outdoor unit and look for any oily spots. The compressor has oil in it and it will show up where there is a leak. Look for any pipes that may be rubbing together as this will rub a hole in a line. Look at the indoor coil looking for the same indications. Hope this helps.

Hello
There could be some other reasons for the ice.
1 bad or cracked door seal,have a look at the door seals.
2 Defrost timer may need to be set longer.
3 T sat set to low or not working properly.

Unit may be low on freon also,causing a lower pressure which would cause a lower tempreture,this occurs with a small leak or a pin hole leak.Once enough freon leaks out it will warm up and no longer work.

You can have a leak check done by a service person.

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.

look for possible ice buildup with in the freezer compartment.If you have alot of ice buildup it can block the flow of cold air to the upper chamber..also check your defrost mode some are automatic ..but in most newer and older models if the defrost timer goes bad the fridge..wont cool or over cools..These are fairly common problems in most units .if none of the above fit..its best to call a service tech to your house as it can be a blocked freon line, leaking freon, numerous other things depending on the age of the fridge

there is a leak and need to fix it before you can charge it

You need to have a pressure gauge the reads for R-22. (Freon) It sounds like the system might have a leak. Look for a wet place any place on the units pipe system. It has a little oil in with the freon that is forced out of any leak. If you see a wet place this is oil. It is also the location of your leak.

this sounds like a joint is leaking just but not enough for the water to surface try digging the main line from the meter to the house be careful not to damage any lines under the ground and mind any gas and electric lines. once you find the water line out of the meter trace it to the house as soon as you start digging into mud your gitting close to the leak. once found remove dirt so that repairs can be made
