If the fan motor is not starting it may be the capacitor located behind the electrical panel on the outside unit. These are relatively inexpensive and easy to change. You can disconnect the power to the outdoor unit and remove the capacitor. Take it to your local HVAC wholsaler or contractor and have them check it. If its bad it should run you 20 to 30 dollars to replace. If it is not the capacitor then it may be the fan motor. If the blade turns easy it means the bearings are fine. One of the windings may be open thus making it able to turn but not run when power is supplied. I think this is a heat pump and there may be a control board on the outdoor unit which may control the operation of the fan. I have not found a wiring schematic for the unit yet. Once I find one I will let you know. The problem listed above is very comon and inexpensive for you to fix. If it is something other than the capacitor, I would call you local NATE certified technician and get her looked at.

My outdoor heat pump will not come on. its a upne-042jaz heat pump by can i determine what is wrong?

With out a meter it hard. Check to see if you have power out side in the unit, if yes cycle the unit off and back on with the stat. this will reset the high pressure switch lockout relay, if after the delay nothing, check for a manual high pressure reset, if a manual there will be a button at the top of the switch, press hard while holding the rest of the switch. If this works then you either have a bad fan motor or the outdoor coil is dirty, Take the garden hose with a nozzle to it use, use a solid stream use a much pressure as the fins will take without bending them start at the top and go across working down,

We have a RUUD AC unit, model number UAMB-042JAZ. ...

Those are the low voltage wires from the thermostat and transformer. Yes he can just match up the colors and splice with wire nuts or something else to hold the tight. If the transformer got shorted out during any of this it may need to be replaced. Hook them up and if the unit runs, then no problem with the transformer.

Power outage last night now my RUUD High Achiever AC Unit model# UPNE-048JAZ will not work

Power surge may have taken out your control board (in the furnace, does the fan work?), possibly the transformer (in the furnace) or possibly the capacitor (in the A/C). Call a professional.

Daily reset of outside unit

I have the same unit and was having the same problem. My brother works on A/C's and told me that the coils most likely needed cleaning from the inside out because when they are clogged with a lot of debris the system will overheat and cause that switch to trip and so far it has worked. What you need to do is turn the main breaker off to the outside unit first then take the four screws out of the top of the unit, use a flat head screwdriver and lift the fan it's self up out of the carefully taking caution of the wires going to the fan, then take the garden hose with a spray nozzle and wash the coils from the inside spraying through the coil to the outside and then wash the louvers off of all the debris and this should help.
