Overview
Replacement compressor for the Phoenix R150 dehumidifier — 6.8 kBTU, 50 Hz, R410A. Phoenix part number 4029753.
It is the single most expensive component in the machine, and the one that decides whether an R150 is worth repairing.
What the parts list says
Named as item 8 in the Phoenix R150 50 Hz service parts list, Compressor, one fitted. The same list names the components that fail alongside it and should be considered at the same time:
- 4035949-02 — compressor capacitor (item 7)
- 4031253 — evaporator coil (item 4)
- 4031254 — condenser coil (item 5)
- 4034716-02 — thermistor probe (item 9)
- 4035902 — control board (item 17)
Before you replace a compressor
A compressor that will not start is more often a capacitor, a thermistor or a control board than a failed compressor. Work through the cheap causes first:
- Capacitor. A run capacitor that has lost capacitance will not start a compressor. It is the cheapest part in the circuit and the most common failure.
- Overload. A compressor cycling on thermal overload is telling you about airflow, refrigerant charge or ambient conditions — not about itself.
- Control board and thermistor. A machine that never calls for cooling has a compressor that never runs, which looks identical from the outside.
- Supply voltage. Long extension leads on a restoration site are a real cause of hard starting.
Only when those are ruled out is the compressor itself the likely fault.
This is refrigeration work
Replacing a compressor means opening a sealed R410A refrigeration circuit. In Australia that is work for a technician holding the appropriate refrigerant handling licence, and the refrigerant must be recovered rather than vented. Do not treat this as a bolt-on part.
A compressor rarely fails cleanly. If it has failed internally, the system needs to be checked for contamination and the filter drier replaced — fitting a new compressor into a contaminated circuit will destroy it.
Frequently asked questions
What refrigerant does it use?
R410A, as stated in CCW's record for this part.
Will it fit an R200 or 250MAX?
No. Those machines are documented with different compressors (4028251 on the 250MAX). Check the parts list for your model.
Does it come with a filter drier or oil?
Not stated. Ask us before ordering — you will almost certainly want a drier as well.
Is it worth repairing an old R150?
That depends on the machine's hours and condition. Tell us what you have and what it has done and we will give you a straight answer, including when the answer is no.
Before you order a compressor, tell us the symptoms — we would rather help you rule out a capacitor or a control board first.
