It is possible that the compressor has completley failed and is shorted to ground. The way you check is to access the compressor terminals where the wires hook up. After noting the location of each wire, remove the wires from the compressor terminals. Get a piece of sandpaper and shine up a small area on on of the copper pipes coming out of the compressor. Use an ohmmeter and check for continuity between each one of the compressor terminals and the copper pipe. If you have ANY continuity from any terminal(s) to the pipe, the compressor is dead and will require replacement. If not then check all of the wiring to and from the compressor looking for any possible shorts to ground (wire chafing, cuts, etc.) After that, check the run capacitor for the compressor. If the capacitor is failed, it will cause the compressor to draw locked rotor amps. Generally speaking, the quick way to tell if it is a capacitor or a short is to listen to the unit. If it trys to start for a couple of seconds and the pops the fuse, either it is the capacitor or the compressor is seized up. If it trips the very instant that it trys to come on, it is a short.

Did you purchase a new Ducted Ceiling Unit with the Upper Unit air conditioner? If you are replacing an older mach 3, the ducted ceiling packs are not compatible and you will need to purchase the ceiling pack as well. The ducted ceiling pack part number for the 8333 series Mach III AC is below.
1. Heat/Cool Air Distribution Box - 8330B735
2. Cool only ADB - 8330A733
3. Wall Thermostat (if needed) - 7330G3351
Hope this helps.

The distance of the cord is a big deal, 10AWG Cord would be best for this situation. If you have a 50ft cord, make sure that the cord is not wound up on top itself as this can cause a drop in voltage and a spike in amperage. Is the compressor trying to come on at all? If not, then you may have a problem with the selector switch or the thermostat. If the compressor is humming for a few seconds and then stopping and then trying to come on again, it could be a problem with voltage loss. Anything below 98.5 plus or minus 10% is too low the for the compressor to kick on.

It is possible that the drain hole on condensate pan is plugged and causing water to over flow pan. Remove cover from unit and check drain line.Clean coils andpan as best you can and clear drain hole. Add a small amount of bleach to water in drain pan.This will kill any algea or bacteria that may be growing in condensate water and plugging the drain. Thank you
