In this video I take you along as I work through Mondays service calls Condenser Motor Replaced Annual AC Tune Up Condensate Leak due to Belly’s in Drain Line Like and Subscribe!
Good to see you tookthe time to move the reversing wires underthe wire. With the high cost of these motors, why couldnt they make it rotate in alternate directions using a dip switch. That wouldnt cost that much.hmmm
Thanks for showing us a little bit of how to wire. Should come useful one day. Kind of odd to see the evap coil right after the filter. Useful to see the coil though
It gets kinda complicated digging deep into the capacitor, but from what I understand the capacitor basically helps regulate voltage to the motor as it runs. If the capacitor is too high the motor will work a lot harder and burn up
That was my question too. Follow-up questions: (1) How does a high cap cause higher inrush current? Wouldn't it instead cause the inrush current to last longer? (2) How does high inrush current cause a fan motor to "burn out?" (3) What specifically is "burned out" that would result in a sluggish fan motor? Does the motor have parallel sets of wire windings, so that burning out some but not all of the windings would reduce but not eliminate the motor's power output? (4) What other explanations might there be for a sluggish, oily fan motor? (5) What component in the fan motor is supposed to prevent the oil from leaking away? Would a broken oil seal cause the fan motor to burn out?
@@MsckMatt: When a capacitor is used as a DC voltage regulator, bigger is better... a bigger capacitor filters out more of the unwanted AC ripples. So I assume the capacitor for the HVAC fan serves a different purpose: to store charge that gets suddenly released when it's time to jolt the "off" motor to start it spinning. In general, it takes more force (electric current) to start something moving than to keep it moving, due to stiction (static friction).
Higher mfd cap causing more starting current which puts more strain and heat on the motor windings is what caused this motor to burn up. The motor is specifically designed and built for a certain start and run current. Basically the wrong cap caused excessive heat in the motor, burning up its windings. The oil seal is around where the shaft is. A motor with oil leaking out can still work but it usually means it’s time to replace.
