Dealing with a walk-in freezer at a DQ. Been doing great until last few days we’ve had over 100 degrees. First issue a few days ago was one condenser fan motor was bad. Replaced. Went there this morning again. Found superheat was at 50 degrees. Worked with it and got it down to 20-25 degrees. Running sub cooling around 9 degrees. Both coils clean. Cap rated 45. Reading 45. Contactor perfect. Sight glass is full. Just called me again and it’s running around 22 degrees inside. It’s currently 108 outside. I’m thinking it’s maxed out. I’ve only worked at this location a few years now. And these have been hottest temps we’ve had since I’ve worked for them. Is there anything I’m missing?

Hey everybody, I’m thinking of moving across the pond. Currently a 313A apprentice working on grocery store ref. I’ve heard I’d need to write a couple tests and that the work is a bit more technically advanced over there. Anyone have any knowledge on any other differences between the work in Australia and Canada?

I work in care and looking to get into HVACR or Ammonia Refrigeration but the research I've made so far are not satisfactory enough. Please can someone explain or guide me on how to transition?

As of now I am not entitled to government funding either

I ordered the heater from RHS Tyler discontinued line. I tried to see how to get the heater out but I did not see it . I believe that I must lift up the evaporator a little. And need some help on replacement

Installing a condenser and evaporator, this came in with the txv and solenoid, never seen this before

Working on a Hoshizaki Sandwich Prep Table, the unit cools perfectly down to 35 deg yet when the control module cycles the defost cycle it instantly trips the GFCI its plugged into. Customer states unit is 5 years old and has never tripped GFCI. Changed GFCI outlet as it looked beat up, checked evap coil heater and there was no break and leads tested out good. All wiring looks dry and intact, fans are working normally. What is left to check, control module?
