What refrigerant are you using? with r-22 the high side should be around 230 to 250 psi and suction should be 68 to 70 psi.

SOURCE: have goodman unit, ac unit

You should have liquid line filter/dryer that maybe restricted or there is a restriction in the orfice inside the evap coil normal operating pressures are 68/ 180

first off you should have a four ton unit. what is your super heat? is it pulling attic or outside air?

SOURCE: Charging chart missing. Goodman 4-ton AC (model CK

Hello, if this is a R-22 unit your low side should between 70-75 psig and high side should be between 225-230psig. But keep in mind always measure the superheat if it is a fixed orifice and subcooling if it is a txv unit

Condencer runs for 20 sec then off keeps repeting after 2 or 3 min goodman central system


Seems like it trying to start and then cuts out , possibly on overload. Try the machine on fan blow only , that will check the indoor unit to see if that is working. Then try cool or heat function while listening to the machine starting. If you hear a loud humming just as the fan starts, and then it cuts out, It could be a compressor issue. Possibly the start capacitor has failed.

Why does the compressor on my goodman package unit turn on and off before completing a cycle?


There is several possible causes. The most probable cause is wrong charge. Many units have a low suction safety on the low pressure side of the compressor. There is often a high pressure swithch to guard against over pressure also on the high pressure side. If your unit has the condensing fan stop in mid cycle, the compressor has inherent motor contacts inside the compressor to help guard the compressor from overheating. I just recently had to replace several customers main contactor because the contactor contacts were severly burned and sometimes could pass current and sometimes could not. I also had a few customers whose condensing unit was so dirty that the compressor was overheating causing the inherent motor contacts to open. Hope this gives you some ideas to look.

No suction pressure at condenser test port


i would suspect the valve on suction side not open. if the other system failed on a burn out you could have a blocked dryer or orfice at coil.

Goodman unit runs and at the a-coil there is a piston where your suction and liquid lines connect. On the liquid side the piston is cold but warm on the other side of piston. A/C unit will not cool.


That piston is the metering device. On the liquid line, before the metering device it is always warm (this is sub cooled, high pressure liquid), but should flash to low pressure, lower temperature vapor once it passes through the metering device. The suction and liquid line never connect together.The liquid line brings liquid from the condenser to the evaporator. The suction line brings super heated vapor from the evaporator to the compressor. Since the unit does run, I'd have to put a gauge on it,but if I had to guess, I'd guess you have high head pressure. Check for dirt or debris on the condenser, check for proper clearance of the condensing unit and check for operation and directional rotation of the condenser fan. This could also be the result of an over charge.

Above 78F no longer works gives heat head pressure is 300 and slightly above while low side varies bet 45 and 55 psi,noise in the return. i have about 85 feet of coil run 3/8 high side and 3/4 return from...


Your head pressure is a little high, depending on the ambient temp and your suction pressure is a little low. The suction pressure should be around 68 psig, the equivalent of a 40 degree coil. You can try adding a little refrigerant, check your compressor amp draw. If head pressure keeps going up and suction doesn't come up you may have a restricted metering device or filter dryer

Hello, what is your high side pressure? A bad compressor will show abnormally high low side pressure with abnormally low high side pressure. That 45 low side pressure is low And superheat high. If you high side pressure is normal toma little above normal but the low side remains low you have a restriction in the system, that might be why it's not taking in tne freon. Let me know you high side pressure

NOT COOLING PROPERLY. SUSPECT CHARGE SUPERHEAT TOO HIGH


take the temp and press reading as per manf. and cal actual superheat. what are the reading for amb, evap temp, pressures high low. Then adjust charge. you need to determine super heat based on dry bulb indoor and outside ambient the read suction line temp vs suction line pressure

Have goodman unit, ac unit running 55 suction, 210 high side. cleaned condenser coils and charge to 10 degrees supercool. suction at 65, discharge 245, why did my discharge go so high


You should have liquid line filter/dryer that maybe restricted or there is a restriction in the orfice inside the evap coil normal operating pressures are 68/ 180
