GE profile refrigerator not freezing
« on: August 19, 2011, 06:36:06 AM »
i have a problem with a GE profile refrigerator,model  TFG27PFX[a]  . the refrigerator seems ok, but freezer side does not freeze. the display shows an error code PF. It continues running with the error but no freezing. after running for about 5 hours i found the bottom coil had frosted , but not the upper.can someone please help me on this .and how to get technical data for this model.  and if possible error codes.
Thanks in advance

Check the condenser fan motor beside the compressor. If the compressor is running the fan motor must be running. If the compressor and fan motor are both running you may have a refrigerant leak or weak compressor.

Thanks for the response. the compressor and condenser fan is working, but i hear a slight trickling sound [like water flow] somewhere around the compressor. is it normal or a restriction in gas flow.

Clean up the coils and feel the compressor if it is hot as fire you could have a bad compressor relay. Make sure the fan is running full blast and not slowing down. The trickling sound could be the fan motor going out.

I had cleaned the condenser coils before.the fan speed too seems good.the compressor is warm to the touch. doesn't seem to overheat, compressor draws about 1.8 AMPS . The trickling sound sounds like gas flowing,and the sound varies.can the compressor efficiency be checked without disturbing refrigerant lines.?

That dude probably has a slow leak. What kind of gas does it use?

Can you get  A-1 line tap and some gauges with a 12oz can of R134A? That can holds enuff stuff to do 3 or 4 ice boxes. Sand down the LOW SIDE copper line before installin the saddle valve. The kit comes with a pin. You place that pin on the schrader and then screw down the cap that comes with the kit till it pierces the tubing (if you overtighten the damn thang then the schrader won't retract and all the friggin gas will escape NO GOOD do not over tighten) Then after the install see if you hear a hiss. Press the spring loaded schrader valve with your finger nail  to see if the system is under pressure. A hiss means you still have gas in it and that is good! If it has some in it that means yall can add a little. I mean a little. SLOWLY add a TAD till them fins frost over that evap. NEVER let the suction pressure exceed 5PSI when charging. When adding never let the pressure go over the 10 PSI mark. This is critical! OR yall could buy a fugging thousand dollar outfit to charge the exact amount  :rofl: Just take your time and add a tiny amount. Don't let no air get in the system and Party on  O0

That defrost heater can sometimes create a tiny leak. It might take years to leak out. adding some gas can brang it back. It might take years to need another shot. Just a tad might git her goin. Sometime the lines is redirected down n the water supposedly to help coolig. But water and steel don't live together too well. LOL Leak happens. Click on pix to enlarge them:

thanks for all the help. i fixed a line tap. while working pressure was well below zero, i have topped up to 5psi. current too has increased fro.m 1.8.A to 2.3A and the coil is frosting.there is hardly any space at the bottom to inspect tubing.even the condenser is packed tight at the bottom. moving this ice box is not easy for it's weight.anyway i'll let it run for a day or so and give you a feedback . thanks.
