If the green wire is broke, replace it. that is your ground wire on a a/c unit. Make sure all power is disconnected when replacing

I have an older trane twe030c140b0air handler and it was workingq fine then today froze. Fan in unit will not run. Sparks from conteoller. Is that the correct name? Unit is 208 thanks


Turn power off to air handler. Jump red and green inside the machine. Turn power on. If fan runs then the problem is likely outside of the machine, that being tstat or tstat wire.

WHICH WIRES DO I RECONNECT POWER PLUG WIRES TO?


The colour scheme for the wiring all depends upon the age of the unit or which country you are in. If you're in the EU, appliances usually have blue for neutral and brown for live. If you're in the UK with an old piece of equipment, the live is red and the neutral is black.

Ground is green or green and yellow.

That wire carries the current to charge the battery. If it breaks, the battery voltage will drop and the car will not run correctly, if at all. It may start and run for a few seconds then cut off.

I have a goodman GMP10-5 REV that the blower will not shut off, i think it may be the fan limit switch, can I test it and where is it located?


the older units have the limit mounted on the heat exchanger straight in front as u look at unit. try taping on unit . newer units are on a circuit board . just for the heck of it unhook the green t-stat wire on termal bloc on unit. if the blower stops then replace t-stat.

I need wiring manual for goodman mini split.


outside unit L1 and L2 are load (input 240vac)
then you have control voltage, usually yellow and blue (24vac) this connects to some 18/2 thermostat wire which goes inside as white and red.

note: this unit may only need 24v control which is 2 wires from the inside unit and also 3 wires 2 hot 1 ground for line voltage.

STANDARD WIRING
on the inside unit you have green, white, blue and red control wires.

on your thermostat you have white, red, yellow and green

you run the wire from the outside unit to the inside unit. then run a 18/4 wire to the thermostat if wired and join the following wires.

inside unit thermostat outside unit
green------------------------green
white-------------------------white
red----------------------------red
blue-------------------------------------------------------blue
yellow--------------------yellow

I have a 4 wire thermostat - Red, White, and 2 Green. I had originally marked each wire by matching with the old wired thermostat. I had some AC work done, today. The tech took off my markings. Now, the...


First make sure he didn't accidentally push the fan button to "on" instead of "automatic". If he did, switch it back to automatic and it will soon go off when the compressor stops running.

If that doesn't do it, and you're certain the red and white are properly wired, then go ahead and switch the greens. But I'd turn the breaker off first.
