22TN Heater blocked

My first post as a member.

I recently purchased a 2007 TN and the temperature control won’t go to heat. When I turn the temperature control knob it’s like it won’t go past the cold section and won’t turn to heat. I’ve had it for a week and I don’t recall it having this issue when I picked it up.

Does anyone have any suggestions? Was hoping before I send it in it was just a simple operator error I could remedy.

Thanks

The heater control controller in my G2 has never worked for more than a couple of flights. I think the whole wire push/pull thing is just janky and the set screw isn’t sufficient to keep the knob from spinning on the shaft when there is any binding. No answers except to replace the whole assembly, let me know if you find any secrets to it!

Justin, I had similar troubles with my 2008 SR22TN. The first problem discovered was the heater control box was installed incorrectly on the heels of an engine change. The second problem was the cables were binding and being interfered with by scat hose that was too long and was getting hooked into by the heater control cable.

100% correct. Just went through an engine change and scat hose was pressing against the control wire limiting movement. Just fixed it late last night and was going to post to the forum today so others were aware as well. Thanks for the reply.
