what will using too large of a piston in a FCC (flow check control) type metering device cause? - ANSWERit will lead to too much liquid in the evaporator and could cause liquid flood back to the compressor when starting up a compressor you hear only humming from the compressor and then tripped internal overload. What might be the problem - ANSWERhe most common problem to find will be a faulty Potential Start Relay. If the relay and start capacitor test out good, then the compressor is probably locked up mechanically. too low of delta-t across an evaporator could mean what - ANSWERtoo high of air flow where is the accumulator located on a heat pump and where is it located on a normal unit - ANSWERthe true suction line between the middle connection of the Reversing Valve and the Compressor inlet. and the suction line before the compressor why must you keep the bottom of the condenser clean on a heat pump - ANSWERso that defrost water can drain away from the coil. what is the formula to find the CFM - ANSWERVelocity (FPM) X Free Air Area (Sq Feet) know how to read the friction chart to calculate air flow - ANSWERask burdette
