installed brand new copressor just humms... new cap as well....getting 240 trying to recharge. but comp. wont start.?
i am epa certified type 2
i dont have an amp draw meter with me ....
i located a amp draw meter will test now but yeah i have s to herm on cap and the other lines on either side of the contactor
s is 4.7 left leg is 4.7 right leg is 0
c is 0 r is 4.7 s to cap is 4.7 its a single pull single throw contactor c is on the throw side
im getting 240 across both c and r i have c connected to the pull throw side and the jumper from the contactor to cap is on the same side as c... i looked for a saftey switch but didnt see one ...i did have a problem with the saftey switch on the air handler which prevented the contactor from pulling but bypassed that and the contactor is pulling like it should....should i try reversing c & r ?
cool compressor is running but its not sucking in freon....i have the blue to low side yellow to tank... bottle is open manifold knob open just reading 10 psi. compressor off its reading around 50 psi... is the compressor running in reverse ?
i charge units all the time . i dont understand although this is my first heat pump syatem i have worked on.. i always charge on the low side. plse help me understand
Thanks for the positive rating.Tell me if you have evacuated the system using a vacuum pump, and then tell me what refrigerant it uses, and if it says to liquid charge or vapor charge the refrigerant.To charge the system put the system in cooling mode... and put the blue gage hose on the suction service valve port. then back the valve out all of the way... then after it is backed out all the way, turn it one turn clockwise.Hook the red gage hose to the liquid line service port and adjust that the same way.Hook the center service manifold port to the charging cylinder.Run the heat pump in cooling mode and slowly meter liquid refrigerant into the suction side, (blue hose).
compressor must be running at all times, if the compressor begins to frost at all you are feeding refrigerant in too fast. listen to the compressor, if starts to sound noisy or heavily labored, feed the refrigerant in more slowly
Tell me what refrigerant the system uses
Tell me how that goes.Phil
thats what i did..? im wondering if the air handler is wired wrong from the t stat....it may be in heat mode when i put it on cool.. because it will take a charge when i put it in heat mode.?
