pjsny78 Posted January 4, 2012 Report Posted January 4, 2012 I’m having a problem with my flaps and was hoping someone can help. I have a 95 M20J. When the weather gets cold out I am able to lower my flaps but I can’t get them to go back up. I brought it to a guy who was able to fix it one time. he removed the belly and cleaned the connection on something. He says that it happens sometimes in my model of Mooney, that some condensation freezes and the flaps think they are up when they are down if that makes any sense. I am sure as heck not doing this routine for every single flight I make in the cold. Does anyone have any recommendations? Quote
KSMooniac Posted January 4, 2012 Report Posted January 4, 2012 You might need a new limit switch. I got to buy some new ones last year. Quote
pjsny78 Posted January 4, 2012 Author Report Posted January 4, 2012 Thank you guys very much for your help. would you happen to know how much one of these switches cost and approx. what it would be for labor to install? Quote
pjsny78 Posted January 4, 2012 Author Report Posted January 4, 2012 thanks again jim, you have been great. you dont need to look it up i just wanted an idea of what i am facing. mooneyspace is great. Quote
pjsny78 Posted January 4, 2012 Author Report Posted January 4, 2012 yes thats exactly what the mechanic did originally. it worked at first but when it gets cold it does the same thing. Quote
pjsny78 Posted January 4, 2012 Author Report Posted January 4, 2012 yep but at only a few hundred dollars its alot better than i was dreading. Quote
KSMooniac Posted January 4, 2012 Report Posted January 4, 2012 In my case, I had no problems with mine but during test flights at annual it showed up and got replaced... so all I could do was shrug. Quote
hobbies001 Posted January 9, 2012 Report Posted January 9, 2012 Hi guys. Just joined the site last night while looking for some flap switch info. My flaps went dead in flight in the up position the other day. Test light, 2 hrs. , a good mech, and we had it figured out. Switch in cockpit, 2 relay switches in belly next to flap motor, and a few limiting switches on moving parts. One of my relays were bad, googled #... 4$ online w/3$ shipping. (most places were 20$ tho) I do not have the part # for the limiting switches with me, but they are standard industrial switches that I would bet are under 10$. I was going to replace all of them but my mech. recommnded not as they very rarely go bad. So, hopefully be in the air shortly. btw...anyone have a service manual pdf for m20j's? Thanks. Quote

PTK Posted January 9, 2012 Report Posted January 9, 2012 On the subject of flaps what I do as part of my after landing checklist, is to leave the flaps in the takeoff position. This way they are already in position for the next time I fly. This saves the motor from having to work double cycles. Does anyone else do this? I'm also researching and devising a similar checklist item for the gear motor!! Quote
hobbies001 Posted January 10, 2012 Report Posted January 10, 2012 Thanks for the greeting. Looking forward to using the site, and meeting some Mooney folks. I came across the manuals for the M20J including parts, and electrical. It has been a big help finding these. Sure they will come in handy in the future....

hobbies001 Posted February 2, 2012 Report Posted February 2, 2012 My flap problem is fixed. It was one of the limit switches that failed. That caused a relay to burn out which in turn caused the flaps to stop working in any direction. Google search for the relay was 4$ and the limiting switches was 20$ because minimum order was 20$....so I have 9 of them now. lol. Only time consuming issue was making sure flap indicator was correct. Had to adjust limit switches by sliding them up 1/8 " at a time. No problem really just took 20 minutes. Quote
