The temperature outside and pressure chart are needed to accurately determine the proper charge. (temperature pressure charts to calculate heat gain) However the low side of the unit should read around 70 and the high around 210. This is a really broad generalization and I do not recommend you charge your unit just on this info. It will get you close if you are using R-22 and the unit is properly cleaned. A dirty evaporator coil will cause a severe low pressure reading on the low pressure side.
Can you use a 410 AHU with a r22 condensing unit
Yes you can if the 410 a/h is new just put a r22 txv on it I have personally done hundreds of them mainly carrier they even sell the conversion txv.

Malfunction of electronic operation
The electronics of these systems work with a switching power supply.Stress on these power supplies causes destruction of high voltage capacitors or switching I.C.s. To solve the problem search for malfunctioning components and replace them or use a brand new control board.
Fan not running
Which fan are you reffering to? one inside or one outside? do you have a multimeter with a capcitor tester? symbol '( . something like that. let me know i'll walk you through some test
No reading on thermostat
Hello, there could be a few reasons for this. A condensate safety switch may be tripped due to a clogged condensate line, this will involve cleaning the line with a wet/dry vac.
No power to the thermostat due to a burned out transformer or fuse
Dead batteries if the thermostat uses batteries
My condensor fan and compressor on my Carrier AC (Model# 38ckc036350) stopped working, so I replaced my capacitor and they both work fine now. The problem is my house won't cool down. There is c
Often after a repair has been made, the air conditioner will take hours to readjust back to normal. When the system has been off for to long, not only does the heat in the house rise, but so does the humidity, which has to be pulled out of the air first before it really starts dropping in temp. You could have a low charge on refrigerant, dirty filters, etc. More than once I have ran into things that were just coincidence after a repair that showed up. Since you just replaced the capacitor, I would make sure the fan motor is turning in the right direction and there is nice air flow coming out of the condenser, some times if one wire is wrong, it can cause it to spin backwards, which will work, but just barely. The air needs to be pulled through the coils, not pushed. Hope this helps!
