The best thing to do would be to recover the 404a into a clean recovery jug,weighing how much you take out. Check the nameplate on back it will tell total ref charge. in either oz or lbs. then weigh the charge back into the unit. this is the best wayto verify if you have a proper charge.If the unit is low on charge then you will want to find and repair the leak as soon as possible.

Compressor hpco code comes up on panel of Taylor soft serve ice cream machine? Does that mean lack of water to machine?


There is a very good chance. Often the water has been shut off, or a wheel is pinching the hose.

HPCO stands for High Pressure Cut Out. The high side pressure is regulated by the water valve on water cooled equipment.

These are links to parts in the water cooling system.

Compressor hpco


Compressor hpco or (High Pressure Cut Out) means the high side pressure has went over the limit the machine has been set too. The safety is there to protect the compressor. If the machine is water cooled, the water flow has most likely been interrupted. So often the machine was moved for cleaning and the wheel is on the water hose. If the machine is air cooled, Either 1. the fan has stopped, 2. the condensers are dirty or 3. It's just too hot where you are trying to run the machine.

Taylor 8756-33. Which components operate in standby mode?


In standby mode, the machine just wants to keep the product refrigerated until it goes back into auto.

So, the mix cabinet needs to keep the product cool in the bottom of the machine, that requires the mix compressor and fans to run. The mix cabinet temperature is read by a thermistor probe and regulated by the (left side) logic board.

The product in the cylinders should go back to liquid form in standby, but we still have to maintain that safe food temperature, the motor and compressor will run periodically. If the machine is air-cooled a fan will run anytime the compressors run. If it is water cooled, water will flow through the machine when the compressor runs. The temperature in the freezing cylinders is read by a different thermistor probe and regulated by the logic boards.

Here is a link to all of the parts in a Taylor 8756.

Hello I have a 8754 Taylor and having trouble with the (chocolate)left side of the machine.The product goes soft after I've served about fifty cones. this is what I've tried *installed all new o rings...


sounds like a freon like to me if the compressor is running for long periods and not freezing properly or you have a water pressure issue. if it is water cooled which alot are it is hard to realize you have a freon leak.

Soft serve machine freezing solid


POSSIBLE CAUSES• Mix hopper is empty, freezing cylinder starved for mix.• Mix in hopper contains ice particles, mix feed tube clogged.• Machine turned too cold

ACTION REQUIRED• Add mix to hopper. Put machine in wash mode to help thaw freezing cylinder.• Pull mix feed tube to fill freezing cylinder. Replace mix feed tube and put machine in wash mode to help thaw mix in freezing cylinder.• Follow manufacturer's recommendation for the proper temperature for the mix being used.

I hooked up my gauge run the unit and sees the high side pressure goes up, the compressor overheating and shuts off. I checked the water pressure regulator valve it good. so I unwelded the condensor coil...


It sounds like you may have unwelded the suction line to the compressor and blew the compressor out. That is not good. How a Taylor works is this: Compressor comes on and produces a lot of heat. There are 3 ways to dissipate the heat. If there is a big radiator like set of copper and aluminum finned coils near the compressor it is air cooled. If there is a water line going in and a drain line coming out, it is water cooled, the water runs the whole time the compressors are running, the third way is to have an outside remote condenser coil. I believe you have a water cooled machine. On the back of the machine is a copper fitting to hook up the incoming water lline. There is also a drain line and water will flow constantly from it if everything is running alright. It is ok for the compressor to get hot when running, it is supposed to get hot. If you broke into the freon lines by mistake, the freon is gone and it won't show pressure anymore. I don't see any way that oil would have gotten into the water cooling line. To verify which is the cooling water, the copper lines will go into the back of the machine and will be wrapped around the outside of the compressor and then back to the drain at the back of the machine. If you blew the oil out of the compressor it will very soon lock up and be destroyed. Look at the line that you cut into.
