Fridge motor on too much it seems

r134a gas is r134a gas and it is used in a variety of applications
because it is a extreme high pressure gas , it is unlikely that you will get a small can of it
It will be cheaper to have a fridge technician come and use the right amount as it normally comes in a 9 kg bottle and cost plenty
a fridge may use 100 grms if lucky

If its the compressor, the compressor is bad and needs to be replaced, typically when they do that, they will short out, and trip the breaker.
It could be the condenser fan motor going bad too, knocking/pinging noise seems more suspect to a fan motor going out or a bent fan blade.

Recommend a appliance repairman to look at this

U need a new fridge. U cheap ***

Hi,

As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Hi,

That is typically a sign of a problem with the heat exchange, specifically the suction line and capillary line have separated OR...the system has been worked on recently and been over-charged with refrigerant.

Answer me these questions...

Is it frosting up close to the compressor ? Where it comes out the back wall at the top back corner only ? Or the entire line all the way down to the compressor ?

Has this fridge had any system work performed on it recently or has anyone "topped it up" with refrigerant ?

What are the temperatures in the fridge ? Are you capable of gauging/measuring system pressures ?

Finally, how old is this fridge and do you know if it contains R12 or R134A ? ...if it`s old enough for R502, forget it ha ha !

I`ll watch for your reply.

HI,

if the compressor is running your ref. should be getting cold. Their is a defrost timer but when it is in defrost the compressor shuts off. I think you do have a leak.

thanks,

Unfortunatly in most cases it is more expensive to fix than replace. A compressor change is at least 3 hours. The other cost include the compressor, drier, recovery machine, recovery cylinder, silver sodder, torch fees, and so on. The compressor will likely cost around $300. A used fridge in the paper can cost less then $200. Please let me know if you need anymore information.

Hi i had the same problem and someone came in it was well worth it it was the relay button and it only cost $50.00 for the part .

the motor could be on the way out. Put your hand (carefully) on the motor (back of the refridgerator), if it is too hot to touch then the motor is burning out and will need to be replaced.

the compressor has a loose or broken spring inside the compressor, unfortunatly it can not be repaired without replacing the compressor, it could last many more years and it could quit as we speak.

best thing is to let the neighbor know of the problem and what is the repair that way they won't think you are ponning off the machine to them, it may outlast your new one, time will tell
