Cruising the St. John River, virtually no marine
System has a separate box for fridge and freezer
If I run freezer
box with the thermostat in the fridge off, it chills normally, down to zero if I want. No clicking sound
If I run both, neither chills. Clicking sound
If I run fridge alone, it does not chill. Well the plates get just a little cold, but basically that box could be a freezer too if I let the system run. Clicking sound.
Clicking sound coming from the T fitting which I assume is the low pressure return for both fridge and freezer. Has larger tubing going into it, much larger than the high pressure tubing coming out of the two solenoids.
I spoke by phone
to my fridge tech, he thought it might be a sticky solenoid and suggested a little percussive maintenance
. No joy. Clicking is not coming from the solenoid anyway. I tried tapping on the T fitting too.
Is there some kind of one way valve in that T fitting that is not allowing coolant
to flow on the fridge side?
System worked at the beginning of this trip and has worked flawlessly for years, other than consuming beaucoup amps.
Any other suggestions I can try myself? Have no refrigeration
tools on board.
