      [Webinar] Samurai's Sealed System Sleuthing Secrets - 10/30/2017 @7PM ET   10/19/2017

      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

can i use automotive hvac guages too work on sealed system of a refrigerator. Are the hoses on the automotive hoses compatible with shrader valves, saddle valves, etc.....?

Depends if the gauges are for the old R12 refrigerant or the R134a refrigerant.

R12 gauges will hook up.

134a will not.

Threads are the same except for the old R-12......I hate it when you go out on a service call for not cooling ....You check the evaporator coils and see no frost pattern.......Upon spinning the refer around, you see a 'Bullet tap' on the system........The customer sez ( in a bid to save money ) " I had Bob's Used Auto Sales and Used Appliance" guy fix it " Now , ya gotta tell the customer how much it will cost to fix it correctly............. P.S................I use a ' four way ' set of gauges, ( promo pitch, Yellow Jacket.....10 years of service and a high side gauge just broke) ................. 1) high side................. 2) low side.........3) vacuum pump and 4) hook-up a refrigerant tank for a sweep charge or a vacuum gauge.......or........................ P.P.S.....use low loss fittings, less chance of non- condensables from entering the system.... .

Wait a sec.

Automotive service valves for 134a are going to be either quick-connect or Acme thread. The ad said something about "manual couplers"? What, adapters or something that you aren't using for this job?
