24,000btu split wall equipment

Hello forum friends. I have the following problem: a Kendal brand 24,000btu split wall equipment. The problem is that this equipment leaks a leak in its 4-way valve losing all its R410 refrigerant. The valve is hostage repairing the leak. A sweep of the mechanical lines was performed with nitrogen. It was performed empty to the complete system. The equipment was charged by weight. The problem is that in cold mode with a pressure 105psi r410 the high line cools the same or more than the low suction line consuming around 9.5A. And when you put the unit in heating mode, the 2 high and low lines get very hot. Consumption rises to 12Amperes and the pressure reaches 580psi. Here the equipment stops and stops working this lasts about 3 min. Approx. In the same enclosure there are 2 more teams of the same characteristics model, brand, capacity. We exchange outdoor unit and the problem is identical. Which leads me to assume that the problem is in evaporator. Anyone know what may be happening? Thanks in advance...

Hi Gustavo, cut by thermal?
That only the compressor stops?
In cold temperature did he have that pressure?

If it cuts by thermal.
Indoor and outdoor unit stop.
In cold I have 105psi.

The strange thing is that you changed the outdoor unit and the fault continues.
The equipment that you changed the external u worked well?

Yes. That unit is operational. The place is a restaurant and I can't see the indoor unit yet. And how I make that change to the outdoor unit leads me to think that the problem is in the indoor unit.

The only drawback of the interior is that it is flooded with oil.
The other is that the spout sensor is devalued or broken.

Always do the same with the other and outside.

I will check the spout sensor and if there is oil. And I will comment how it goes!

Hello how are you, many teams when working in heating mode raise the amperage and stop the outdoor unit formator but when stopping all the equipment for high pressure protection it may be because the indoor unit is dirty and more if it is in a restaurant where in the environment there is grace the turbine evaporator can be covered and generate this problem greetings.

Thank you. I still can't enter the indoor unit. We usually maintain these equipment every 3 months, which is 3 in total and, unlike others, they are kept clean. Now I will not discard your advice.
I created that perhaps the spout sensor was devalued. But is this apart from teaching the evaporator fan what other function does it fulfill?

Turn on the evaporator in heating mode, and detect lack of temperature and coolant pressure for the latter
