SOURCE: Model # PSC25PSTBSS low pressure tubing icing up

Very unusual for a household fridge, but ice build up on the lp side(suction) normally indicates to much charge (gas) in system or if compressor starts to become less efficient, valves dont seat 100% which causes a liquid build up on the line. If the evaporator fan motor stops, this can also create that problem.(assuming the fridge wasnt cooling properly). Many occasions when a new compressor is installed, the technician might put a little to much charge in by mistake. Normally a machine puts in an exact amount that has been dialed in.

Hi,You have a restriction and will need to remove it so the unit will function correctly. Use a strong vacuum over night too clean and dry out the system. Sometimes this works, other time I use nitrogen to clear the restriction, it's a pain and extra work but a very clean system when done. I hope this unit is yours, it can be costly to a consumers to cover you time.
Good Luck

How much it cost to replace a compressor on True Deli-Cases TSID-72-l2


Your looking at a Job that takes about 4 to 5 Hours of labor. Reclaim machine,Vacuum pump, Torch, Silver Solder, Freon, Nitrogen,Liquid line drier, Possible suction line drier if it was a shorted compressor windings. New start components. and then maybe a cap tube depending on what caused the compressor to fail. So with that said you can expect to spend $1500 to $2300.

Does not cool technician says cooling unit is "blocked" needs to be replaced. should we just get a new frig?


Tell him to remove the strainer, remove cap tube, blow out system with nitrogen, install new strainer/ filter drier, install new cap tube and charge, you should be as good as new. Hope this helps.

Hello Sometimes there is a SCREEN in the liquid line just b4 the piston in the tube.You had a SEVERE burnout the filter driers are shot from doing there job even with the short run time.Also you could try pulling the piston out and blow out the cap tubes in the evap.Close the suction service valve and pressurize the pipe and let it blow out the piston holder ot help clear those tiny tubes.Use a OVERSIZE liquid drier this time,Get a 10 ton drier or better.

NOT GETTING COLD ENOUGH 25 DEGREES CLEANED


High suction pressure is telling you there is a blockage in the coolant system usually. It most often occurs at the drier. If the drier is clogged it will cause the symptom you describe. This may sound crazy but take two wooden handles (hammers whatever) but WOOD and strike the drier simultaniously. (I.e at the same tame with the handles. Don't be afraid to give it a good whack.. just don't dent it or the lines. It may or may not snap out of it. Additionally the capillary tube can cause the exact same symptom. You have coolant flow.. just not enough.

You may sadly have to have to system bleed off (recaptured coolant) and purged until restriction vanishes with nitrogen if you can not find the current restriction. These can be real easy or a nightmare there is no in between.

Thanks for choosing FixYa.

Obd-2 code p1455


DTC P1455 - Substantial Leak or Blockage in Evaporative Emission Control System

The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).

Check this possible causes:
After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube
EVAP canister purge valve stuck closed
Damaged EVAP canister
Damaged or missing fuel filler cap
Insufficient fuel filler cap installation
Loose fuel vapor hose/tube connections to EVAP system components
Blockages or restrictions in fuel vapor hoses/tubes (items also listed under disconnections or cracks)
Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
Canister vent (CV) solenoid stuck open
Mechanically inoperative fuel tank pressure (FTP) sensor


Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank

Tell us news.

Frigidaire FRS26F5A fridge at 50 degrees


You will have a blockage in the ferfigeration system. Its not a big deal, a technician needs to regas the fridge. Make sure he installs a new drier before he pumps gas into the fridge. (When the drier is contaminated, it restricts gas flow). This is what you have with your fridge..

Ac capillary tubes


Sounds like you have a clogged cap tube. Yes they should both be sweating, I would expect your low side pressure to be lower though unless it is real hot in the camper. You can replace the tube but make sure what goes in is the same diameter and length because that is all engineered for proper metering into the evaporator.

Capillary tube replacement


The True TSSU-60-16 uses an oversized (134A) refrigeration system with air flow directed at the pans.... if the capillary tube is plugged it will NOT cool at all.. most of the time a restriction (plug) is at the drier where the capillary tube goes into it.. as it is smallest passage in the system...hope it helps
