Let it warm up overnight and It did just fine the following day. This is the second RTHD 2009 that Ive had both oil solenoids leaking from the top, like someone used a can opener on them. I've seen the 2003 bulletin that said they "got rid of those valves and since then have had no problems." Now why did they make a confidential SB that said pretty much the same thing except for dates? (and also paid for the parts and some labor.) It looks like they really didn't get rid of the "bad" solenoid valves just slowly put them back in the system. I find it odd that my customer is out a ton of cash for refrigerant and parts that should have never been put in in the first place. In over 30 years of commercial service, I have yet to see this kind of failure, nor can I find any other seasoned tech to say the same. But anyway they are both working fine except for some more refrigerant to bring up the charges before summer.
    Are you talking about the gas pump solenoids? I would like to see the confidential SB.

    I going through all the RTHD post I can find before I do a gas pump replacement. The correct reading is "wet" for the oil optical sensor when its covered with black electrical. I just dont want someone to be confused.

    I agree with Healey Nut: If it isn't splattered on the walls or in a big pool under it- it's in there somewhere. Don't put more in- work out where it is and how to get it back
