Goodman heat pump aruf estrips on all the time

Is this a 2 stage cooling system because only then you will need y2.
You can put any color you like on these terminal but it have to match up with the thermostat for example if you put black on R terminal on air handler then you have to put black on R on thermostat

spray with soap bubble solution let sit hour then check

your heat-relay aka heat sequencer, time delay... is stuck most likely remove and replace if it checks closed and no 24 volts is going to the timer portion.for 3 to 5 minutes. some of these switches stay closed for 3-5 minutes.after power is removed

Hello, Usually it has to do with the quality of the install and the brand. If it was not installed properly from the beginning then the equipment will fail prematurely. As far as the heat exchanger goes I have replaced many heat exchangers on Goodmans after 3 years being installed, Goodmans are prone to bad heat exchangers.

that purple wire goes conected to the black wire that is connected on the sequencer to send the signal to the fan blower.

Heat pumps are like a refrigerator. Check the "pump" part is working properly. and is cooling one side, heating the other.

If not - maybe run out of gas (needing technical repair and refill) - or a motor fault.

all heaters smell that way after a long time of not useing it, it's the lint and hair ,dust built up in the unit,clowny daggers

MY MODLE NUMER IS CPLE42-1 SERIAL NUMBER IS 010940037

remote heat pump tries to start, but quickly times out

You may need a "current sensing relay" to clip around the neutral wire on your blower.
Run the 120v power to the main power (the power switch- hot,neutral and ground) . Run the Hot wire through the "Current Sesing Relay" wires to the EAC unit's 120v. power input. The unit will only run when the fan is on.

Hope this helps,
Matt
