Heat pump condenser fan
I have, what I hope, to be an easy question to answer. I have been search but can't find anything that matches my issue.
I have a Nutone Heat Pump model number FTBF-024KA. The outdoor compressor fan stays on except when I turn the heat on. Didn't notice the issue until it started to cool off, all summer the fan seems to always be running but when I turned the AC off the fan stayed on so I turned the heat on and the fan turns off, and stays off. I let the heat run for about 20 mins and the fan never turned on. But when I turned it off the fan started spinning again.
I don't have the money to call a technician right now and if it's something I can easily do I would like to try.
Thank you.

Welcome to the forums.
Nortek owns Nutone now. I don't see any information based on what you posted as a model number.
Is it just the condenser fan running and not the compressor too ?
Try posting a few pictures of the controls inside so we can get an idea of what you have.

Here's a link to four images........ Picture link
The condenser only runs if I turn on the AC or Heat.
Just the fan stays running unless I turn on the heat, then the fan turns off.

You did not post the model number correctly. You have a FT4BF-024KA.
I posted two links below. Download them for your reference.
What you will need to do is to disconnect power to your outside condenser. Disconnect the three fan motor leads. They are orange, blue and black. Using an ohmmeter check from each wire to ground. There should be no continuity measured. If there is..... the motor has a shorted winding and will need to be replaced. Be sure to ID where you remove the wires from.

I completed the continuity check on each wire and only thing it displayed was OL, no beeping. I did a check on L1-T1 which did have continuity, and L2-T2 which didn't have continuity unless I pressed the plunger down. I downloaded the manual and diagram to try to figure things out. Which is a little off because I have a Comfort Alert UltraTech Diagnostic that the wires lead to first.
I also found out that I have a module (googled this info after I typed in the right info) inside the unit which I took a picture of https://imgur.com/a/5e59PKS, where the wires lead to, and from the module to the fan.
Any ideas from here? And thanks for the help so far I appreciate it.

The part where it says fan motor is a module that attach to the back of the motor. The motor and the fan are hanging down and the module is attached the inside of the unit. I guess it it's technically a motor part I'm assuming, I read it as module. it's ECM 142R.
King of like this picture (not my actual unit).
