Connecting pipe vibrates
due to improper
installation, or touch the
lower frame
Check the connecting pipe
Tidy up the pipes,
eliminate the noise source
Outdoor pipes touches
Check the vibration of the
pipes, check if them touch
Tidy up the pipes
Abrasion of the parts of
compressor Check if the sound of
compressor is normal
Replace the compressor
3.4 Frequently switch on/off of the compressor
Reason Check to be made Proposed remedy
Running voltage is too low Measure the voltage
Add measures of voltage
stabilization
Discharge temp is too high
caused by insufficient of
R407C, compressor is
protected by overheat Check condensation of air
intake pipe or measure if
operating current is lower
than rated current
Check leakage point,
welding or add R407C
Temp sensor is too close to
evaporator or moved Check the position of
sensor Adjust the position or
replace the sensor
Air inlet/outlet of heat
exchange is blocked or low
speed of fan motor; indoor
air filter is too dirty or
blocked
Check indoor/outdoor heat
exchange, speed of motor,
air inlet/outlet
Cleanup the filter, remove
the obstacle
Too much R407C
Too much condensation
water on air intake pipe,
high operating current
Discharge a little R407C
Bad insulation of
compressor, high operating
current, overcurrent proof
Check start or operating
current
Replace compressor
Improper temp set
Check actual ambient
temp
Reset
3.5 Promptly protected by halt after compressor starts
Reason Check to be made Proposed Remedy
Insufficient R407C
Little or no condensation
water on air intake pipe,
operating current is lower
than rated current
Add R407C
Mixed with air in the
system, vacuum is not good Power varies when
running Vacuumize the system,
recharge R407C
