Furuno gaas fet front end 4 tone display 16 mile radar scannar not turning
Scannar turns intermitantly,tried uising electronic cleaner spray on it.It worked for awhile.Now with dome off you can start the scanner moving with a gentle nudge but it soon stops.Is the motor gone and if so where can I get one?It worked great until this.And when it turns I have a real good picture.Any suggestions?

If the unit is new and never been set up post installation, that's probably your problem. You have to go into the Installation Wizard and set the unit up properly. There are multiple choices of displays and scanner units to select to obtain the configuration you have. Then the radar has to be optimized (auto-tuned). If you don't have access to an installation manual and feel confident yourself, you'll need to contact a local Furuno authorized dealer or call Furuno USA tech support and they'll walk you through it. Their number is 360-834-9300
Either a weak magnetron, water in wave guide or most likely radar settings are not right.
You have an 1834C, so a 4KW dome, right?
Radar antenna should be set to type "B" in Radar Set-Up menu
Access this menu by holding the Menu button during turn on and then choosing Installation Mode, allowing access to Installation Set Up Menu, where the Radar Set Up Menu is located. Be sure to do Optimize Radar, while you are in there.
Learn to use Sea Clutter and turn off AC Auto Tune.
Good Luck!

unplug the radar from it and turn on the display. If that does not blow the fuse, then your problem is either in the cable to the antenna or the antenna itself. Start there.
ahh, this is an old one
check the book.(ha, ha)
Press and hold menu during start up
Choose "Installation Mode"
Press "Menu"
Select "Radar Set Up"
Press "Next Page"
Select "Radar Heading Alignment"
Use knob and follow prompts, you will place the dotted line at dead ahaed and the
Select "Set"
Also, remember to TUNE VIDEO
A 1942 is a 6 kw radar a 1720 is either a 1.5 or 2.2 kw dome. The two
will not work together. Besides the cabling is different. Also the
radar cable on a 1942 is round where as the 1720 is square. The 1942
display should work fine on a 1943 navnet radar.
You may have a faulty magnetron or one that has gotten old. They do have a life. Find out how many hours you have on the unit and give furuno a call. They will more than likely tell you what they think the problem is.
