Frigidaire ffhb2740ps4 compressor freon and oil leak

most fridges are a sealed system from the factory, and are not able to be serviced. Generally most compressors require pag oil with freon. The freon in the transportation industry is R-134A with R-12 in older vehicles. Household have R-44 and R-22 in older appliances. There are a few different types of pag oil for each application.

check lines for leaks, check all components. If the compressors kicks on then check lines if the compressor doesn't then that's a potential problem as well. If everything; lines, compressor and expansion canister are looking good then your out of freon, it is the gas that is used to transfer heat from the compartments to outside. Having no freon further tells you that you have a leak, since freon is expensive depending on how much your appliance requires, its best to check everything first before you start removing parts from the appliance

If it's compressor oil you would have lost your freon also and the freezer and fridge would stop cooling. It's covered by warranty so get in touch with them.

Either you have some sort of leak and there is no freon pressure or..Your compressor wont turn on because of a swith or control isn't telling it to..Does the fan still blow?

Hi, absolutely there's refrigerant (freon) leak check your condenser and evap. for rupture (broken lines) also check for oil, presence of oil means, refrigerant (freon) leak, plug ref, and listen, for hissing sound inside and outside of ref. try to locate leak, or call mechanic, repair leak, change filter drier and recharge, if your evap punctured, you should immediately disconnect ref, and dry all water from evap, prevent water from entering system, could damage compressor, or if water get into compressor, you will have to change compressor oil. yes, you surely have a refrigerant (freon) leak.good luck.

hi friend,

3 possible reasons ...1 thermostat is bad or is set to high....2 bad compressor start relay or bad compressor...3 freon leaked out...when you plugged it back in did compressor run...if no check thermostat....check relay..its mounted on side of compressor...if yes then low freon...

thank u for using fixya

The 5.7l has a low pressure on off switch. if you freon is low it will not allow it to turn on. This is a way to protect the compressor. By jumping that compressor switch, it will turn on and blow hot because there is no freon AND NO COMPRESSOR OIL!!!! don't do it very long or you will trash your compressor if it is not already. Most vehicles these days have this safety feature.

If your compressor is running with no freon, It should be very hot. Check if it is. And if it is and the freon has leaked out. Then you must find the leak in the system before you add more freon. If you dont this will be an ongoing problem. The freon will leak out after any length of time. This is a very hard task to find the leak, and you will be money ahead to buy another if you dont find the leak than to re charge every year or so.

that year had a bad deighed compressor that leaked at the seams,most likely out of freon/be sure to add pag 150 oil also cause if it leaks freon it leaked oil

Was this unit placed on its side or back? This can cause oil to get where it shouldn't and block freon flow. If the unit has not been moved this is not an issue. Could be the compressor but sounds more like low freon level. Most leaks happen when units are turned off for long periods. I don't ever believe in charging a deep freeze unless you can positively say you have found and fixed the leak. You can never really trust it again and the food inside is usually worth more than the freezer.
