Why is my Trane RAUL 190 Heat Pump compressor noisy?
A noisy compressor can be caused by broken components within the compressor, which would require replacing the compressor. It can also be caused by uneven liquid flow. In this case, check the superheat setting and the fixing of the expansion valve bulb.
What causes insufficient cooling capacity in my Trane RAUL 190?
Insufficient cooling capacity can occur if there are excess pressure drops through the filter drier. Check the refrigerant circuit tightness and add refrigerant. Another cause can be a clogged drier filter, which should be replaced. Also, the superheat may not be properly adjusted. Check the superheat adjustment and adjust the thermostatic expansion valve.
What to do if Trane RAUL 190 Heat Pump discharge pressure is too high?
If the discharge pressure is too high, it may be because the condenser is abnormally hot. Check the operation of the motor fans.
What to do if my Trane RAUL 190 compressor keeps running?
If the compressor runs continuously, it may be due to excess load on the cooling system. Check the thermal insulation and air-tightness of areas requiring air-conditioning.
Why won't my Trane RAUL 190 Heat Pump compressor start?
The compressor may fail to start due to several reasons. The motor or coil might be burned out, requiring replacement or repair. There could be a power cut, a blown fuse (check motor insulation and replace the fuse), or the main power supply might be switched off. Low voltage may be the cause, in which case you should contact your power supply utility. A regulation circuit could be open, or components may be damaged. See instructions for 'discharge pressure high'.
What to do if my Trane RAUL 190 Heat Pump compressor stops?
If your compressor stops, it could be due to several reasons. The discharge pressure might be too high, or the voltage may be too low, requiring you to contact your power supply utility. The cooling demand could be too high, or the condensing temperature could be too high. See instruction 'discharge pressure too high'. Also, there might not be enough cooling fluid. In that case, repair the leak and add refrigerant.
What causes loss of oil in Trane Heat Pump compressor?
Loss of oil in the compressor can occur if there is not enough oil. Contact the Trane office before ordering oil. It can also be caused by a clogged filter drier, which should be replaced.
What to do if my Trane RAUL 190 Heat Pump compressor stops just after starting?
If the compressor stops shortly after starting, the filter drier may be clogged. Replace the filter drier.
What does it mean if suction pressure is too low on Trane Heat Pump?
If the suction pressure is too low, it may be due to excessive pressure drop through the filter drier. Replace the deshydrator.
