Hi
Got a problem on a 18,000btu R410a Wall Mounted Split Heatpump System.
Customer said system not blowing out enough heat.
Attach guages and amp meter, find system short of 410a.
Vac system out add 1.65kg's of 410a notice outdoor fan motor
starts operating with compressor then stops. Does not run again,
compressor reading 350 psi and running amps of 6.5.Suspect faulty
pipe sensor after removing 4 pin plug that controls condenser coil
and pipe sensor ( dual plug ) fan motor operates at full speed.
Guage pressure reaches 500+ psi. running amps 8.0 as per name
plate, do I have a faulty pipe sensor/coil sensor.
Checked omh's reading on both sensors but not giving an indication
on meter from either. In coiling mode system functions O.K pressures
all O.K. and amps O.K.Condenser fan cycles O.K. with sensor plug
in place. Reversing valve operation is O.k but customer still not
happy with temperature from indoor unit.
System is 5 1/2 years old. Filters clean coils clean.
