    Bovine excrement. The capacity of a given system is based on the mass flow of the refrigerant being condensed and evaporated. Mass flow is controlled by the displacement of the compressor, which is...

    The number one problem with DIY on here IMNSHO is that we can't verify your credentials/knowledge on a case-by-case basis, and worse we can't verify the credentials of someone who does a search and...

    It back feeds because of how multi-speed PSC and shaded pole blower/fan/centrifugal pump motors work, they have an auto-transformer integrated into the run windings and intentionally under-volt...

    My point was that if the inverter is starting to trip off then either A. your DC wiring is too thin or B. you are over-discharging the battery causing its internal resistance to rise.

    If it is B...

    The inverter's low battery cutoff is working as designed. You really don't want to draw a true deep cycle lead-acid battery (read medical AGM or gel or golf car flooded) down below 50% SOC, and for a...

    The only way I would use them is with isolation, IE condensing unit outside with a hydronic loop linking it to the house or building. The pressure relief valve would be outside too in case a...

    The problem with that site is that it uses a constant voltage source and dropping resistors. LEDs are current driven devices and their voltage drops as they heat up. If this will be used where you...

    Yep. My parents showed me this video. A short explanation on why 12000 BTU/hr is called 1 ton of cooling cleared that up really quickly.

    BTW I hate faux science videos on YouTube if you can't...

    It sounds like they are labeled as common on the dual run cap not common of the motor itself. IE "common" goes to capacitor common and "cap" goes to capacitor fan.

    It's stumped me. Failed 3uf 370v from an early 80s Emerson single speed ceiling fan, top bulged hence terminals disconnected. No PCBs so I uncrimped the can, drained the oil, and unrolled and...

    Since it's resurrected anyway, has anyone tried using the ribbon burner from an old furnace, seems like it would cover a much wider swath, but then I have never used the fire method personally.

    The condensing coil is all about rejecting heat from vapor at the dew point as rapidly as possible. If the coil is dirty, the discharge superheat is too high so lots of the vapor is above its dew...

    AFAICT if the board says that it will lock out if hot and neutral are reversed then it is getting the flame rod voltage from the AC line, IE with them swapped there is no voltage rod-ground which...
