Question about Coldtech P2SRR-16S Commercial Refrigerator

Open Question

Evaporator coil and vaccuum problem with the P2SRR-16S.

Another company removed evaporator coil and broke suction line off. They said it had a leak. I repaired the suction line, reinstalled the evaporator coil, and sautered the cap tube back in. Now every time I start up the system it pulls into a vaccuum. Charge is 11 1/4 ounces. I pulled evaporator 3 times and flushed. System is still pulling a vaccuum. Is there a regulator or metering device that is supposed to be on the coil, other than just a cap tube?

Motor runs not chilling. Contacted Avanti, they said I need to use a local service person but none are available.


You said the compressor is running? Right? Check for the temperature of the suction line to compressor (line going to compressor from the evaporator coil) - it should be cold. The other line going to evaporator should be nice and hot.

If suction line is not cold, then the unit may have a gas leak and needs to be regassed. However, you need to first locate the leak, repair it, evacuate the system to make sure the fix is good and then refill with appropriate refrigerant. U will need to get a shrader valve to tap into the suction line, a leak detector, leak repair tools, vacuum pump, and refrigerant with manifold.

How do i replace ac evaporator on 1997 gmc sierra


This is not something that is easy, cheap or something a novice should do, you need to have special tools and training ,you have to change the receiver dryer and flush the system. That is why it costs thousands to have it done at a shop.

My goodman unit is freezing up. It is frozen from the line running out of my house than if u look down into unit, the freeze continues inside


Hello, the suction line will freeze either due to low airflow such as dirty air filter, blower wheel, evaporator coil or a weak blower motor. Also, a low refrigerant charge can cause the suction line to freeze up.

Suction line and evaporator coil freezing up


Hello, a air conditioning unit will freeze from lack of airflow or low refrigerant charge. Check filters, make sure blower wheel is clean and running at full speed and that evaporator coil is clean. If that checks out good then you will need a technician to come out and attach guages to the unit to check the operatimg preesures, fimd the leak, amd recharge with refrigerant. Many times the ac will leak at the schreader valves.

I have had a repairman look at this refrigerator and he claims there is a slow leak. Can't a new freon line be installed?


Usually it takes too much labor to fix that line, Kitchenaid built in refrigerators have capillary tube which licks at the back by suction line tube. Refrigerator will need ti be moved out from cabinet in most cases. Tech would want to give You a warranty, so they usually would replace the whole sealed system for big money, but most likely it last 10-15 years. If They will fix one pipe, next year You might call him back, leak might be in different pipe, but it will be the same expensive (due to labor). Check my video out. A Year ago found leak at evaporator, explained to customer better to do the whole system, but he wanted only evaporator replaced since its so obvious. Now we will replace the whole system, Evap is ok, heater too, but now, capillary tube + suction line + drain pan heater loop(freon pipe). If You watch video thru till the end, you will see where heater on old evaporator touching evaporator coil in multiple bents.

Kenmore AC, no cold air


If the evaporator tube is iced up entering the coil and cool to warm leaving the evaporator, that would indicate low on refrigerant or a restriction. If it is iced up entering and leaving the evaporator, then, it could be low on refrigerant,blower not running at proper speed, dirty evaporator coil or filter.
You need to check the suction and head pressure and temperature to determine problem for sure.

Why suction line would ice back


Good day,
Unusual question.
Lots of reasons. You didn't say if it was cooling or cycling off and on.
1. Evaporator fan motor in freezer compartment not running. Doesn't allow the refrigerant to boil off and returns as a liquid.
2. Evaporator coil badly frosted allowing no air flow thru it. Same as #1
3. Runs constantly (days). no demand on system, and once again will not boil off before leaving evaporator.
4. Overcharged. Floods back excess charge.
5. Heat exchanger came apart. The capillary tube is soldered to the suction line to transfer heat from the cap tube to the suction line. Necessary on a refrigerator. Common problem.

Hope this helps
Thanks for using fixYa

Reason for inverted suction line above the evaporator


To keep the freon from flowing back into the compressor, flooding the coil and washing the oil off the rings in the compressor.
Please rate solution if helpful. Thanks

This is ''pops'' moore again!trying to save a $ You helped me before on the firing order.went to a/c guy.he tested system,said evaporator was bad and needed to be changed.his est.was my first born and a...


I assume he used a leak tester and found a leak in the evap which is inside the plenum housing. Need to remove the plenum to get access to the evap. big job. If you are technical, you could remove the plenum assembly and let him replace the evap & then let you out the plenum back in. Then take back to have him evacuate and recharge system.

Evaporator


The following is a general removal procedure of A/C evaporator core. The evaporator is removed differently from different vehicles.
For example, a 1994 Ford Taurus/Mercury Sable instructs you to, "Using a hot knife, cut the top of the air conditioning evaporator housing between the raised outline."

Use a hacksaw or a hot knife to cut the case. Reprinted with the permission of Ford Motor Company.
But a 1993 Ford Probe manual says to simply remove the blower motor and assembly screws before separating the case halves and removing the evaporator.




The following procedure assumes that access to the evaporator has been determined.
  • Recover the refrigerant.
  • Drain the radiator if the heater hose(s) has to be removed to gain access.
  • Remove the heater hose(s), if necessary.
  • Remove any wiring harness, heat shields, brackets, covers, and braces that may restrict access to the evaporator core.
  • Remove the liquid line at the thermostatic expansion valve (TXV) or fixed orifice tube (FOT).
  • Remove the suction line at the evaporator or accumulator outlet.
  • Gain access to the evaporator core as outlined in the service manual.
  • Lift the evaporator from the vehicle.
  • Drain the oil from the evaporator into a calibrated cup.
  • For replacement, reverse the preceding procedure. First, replace the oil with the same amount and type you previously drained.
