    Quick thought dave now with that new 2 speed fan would the differential on tstat have to be more to accommodate for the lower fan speed during defrost ?

  2. Catherine Lachance says:

    Thank you for this. We have been using Trenton Preassembled Evans, which are very convenient. However, they are changing over to electronic TX valves and pile of computer stuff.
    I may start building me own. Liking and saving this one!

  5. the truth says:

    What happened to the super tech symbol. I can't find it . It should be a certificate that you hand out to your Youtubers. Great video you just put out. Believe it or not I got stuck on that same coil, because the wiring diagram was ONLY IN CHINESE!!!! DA FUK!!!!

  6. REFRITEK REFRIGERACION says:

    Yes The first time I wired that fan relay with the solenoid wrong, I said ok I wire them in series. Big mistake, electricity 101, relay coil was getting energized and changing fan speed but magnet on the solenoid was not enough to open.

  7. Rey Rodriguez says:

    The company I work for isnt technically a refer company, but we have customers that have refer equipment so we take care of it. I’ve become a damn efficient refer tech from watching your videos dude. I take care all things refer now, for the company and I do refer calls on the side. Thanks Dave

    I do transportation refrigeration, we had a coil that was slipping apparently, we never have to mess with stuff like that so we had no idea, once the coil was removed we found that the nozzle was loose just rattling around, made the coil ice up

  9. arn mej says:

    good stuff man!…but what kind of thermostat do i need to activated the high speed of the blower again?..i replaced an old evap with similar product just has 3 blower fans…..there's 2 evaps for this system so they used just 1 solenoid to feed both evaps and thermostat is on the old evap…i wired 115 V only to T1 and T2 , blower fans run on low speed ,don't know how to field wire to utilize the high speed…..a little help would be appreciated! thanks
