We just took a service contract over for a customer that has a whole rooftop full of Armstrong equipment, mostly two ton heat pumps. One of the heat pumps that was not working was found to have a bad txv at outdoor heat pump. The bulb was actually broken off and laying in bottom of unit, looked almost like someone cut it but Im sure it just broke from rubbing on something... The model is a shp10c24a-3. The txv on outdoor unit is a alco with gt5659-1 stamped into it. The supplier that sold the hack that installed this equipment is no help in finding the outdoor txv. They have twice now brought me in the txv for the evaporator coil. I cannot find the part number or any info on this txv myself. Does anyone know where I could get one or who to contact? I cant even pull up a parts list on this equipment anywhere online and have had no luck googling a alco parts list. Its a r 22 10 seer system that is about 12 years old... thanks for any help, Im at my wits end here.
