Re: speed resistor on Cold Machine
Longer cycle times COULD be caused by a loss of refrigerant, but there are plenty of other factors that could also cause that symptom. It could be something as simple as the thermostat being set lower than it used to be, or the thermostat sensing probe being out of position . (If the probe is meant to sense evaporator temp and is no longer touching the evaporator plate for example.) If the longer cycle times are a result of a drop in system efficiency then it could be a plugged condenser coil, dirty condenser fan or both.
I am not really sure what you mean by a "speed resistor".
