Catalina 350 New Orleans, La
Hello, my ac/heater unit in my 350 started making noise only when the heater is put on and not the ac. Sound seems to maybe be a capacitor clicking noise sound but could be way off base. Pump is working, air is being created and also working.

I'm attaching pics of the unit including the main electrical box (brains) which is where the sounds seems to be coming from. I'm attaching pics of the unit and the box. Will try to also upload a video of the sounds being made but file might be too large. Anyone with info that can help would be awesome. Thanks in advace.

What is the model and size of your AC unit?
I had similar issue on my 16k BTU.
The Older Units use a special Capacitor that is suppose to kick off as that Capacitors heat up.
