I think I may have a float issue with my DR. I have been running it off and on since converting it to 134a. It has been on for about 2 weeks this time. Last night I thought the compressor sounded strange, not anything bad but different. Also seemed like the evap was boiling louder than I was used to. Frost line was normal so I let it slide.
Tonight I have been out there several times for a cold beverage and it was off each time but frosting normal. The last trip out it was off again, you could still hear refrigerant boiling a little in the evap but the frost was starting to melt off of the evap. I found that the 15 amp breaker was tripped that feeds that circuit, nothing else on that circuit was turned on so I it must have been the Monitor Top that tripped it. It restarted fine but it still sounds strange, ran till it frosted the evap and shut off. Put it on the watt meter and found it was drawing 250 watts when I started it and dropped to 230 when it shut off. That is not been the norm at all.
From what I have learned here This sounds like a float that isn't seating properly, high watts, louder than normal boiling in the evap and just plan not sounding like it is running right = float overfeeding. I wonder if it could be moisture freezing and holding the needle open?

Do you hear the check valve closing at shutoff?

I hear the unloader valve open and pressure balance out several seconds after shut down.
I shut it down for the night and restarted it this morning, still sounds and acts the same. Can't be moisture it would have thawed and work normal for a wile till it froze in the orifice. I just checked my Flikr thread from when I first converted it to 134a and I guess the watts are not really much different than they were then, for some reason I was thinking they were lower before.
I think the real issue is the points in the control are not making good and chattered the compressor on and off causing the breaker to trip. Still seems to sound different but maybe it is because it has warmed up in the garage from last week.

You have the DR in an unheated garage? What size heater are you using?

Try lifting up a corner of the machine about an inch or so and dropping it. This will sometimes work to free the float.

Not sure I have a float problem now, after seeing the watts are about the same as when I first converted it to 134a I think I may have just panicked. I for sure have a problem with the contacts that made it chatter on and off this morning. And yes my garage is not heated all the time. When it was in the 55-60F range last week it was running pretty quiet, now it is warmer and should be a little louder. I still have the 15 watt Supco drain heater #Sh201 folded up and stuffed in the heater well.
