Fixed Hunter ceiling fan with remote light pin out wiring 9 wire plug search words
Hunter Ceiling Fan with remote, fails to turn on light, fails to turn on fan..remote receiver is Cp9430r
1) Test your remote, Hunter uses Radio Frequency remote, point RF remote one inch from antenna of working AM radio, press each button on remote, each button will produce static sound from AM radio, if no sound..check battery wiring or solder connection on loop antenna of remote. If no sound on one or more buttons, disassemble and wash key pad with dish soap, rinse and fan dry, retest. If still one button no work apply graphite paint to button to rebuild conductivity of button.
2) Cp9430r receiver is below fan and above light. Remove light assembly, check receiver dip switches, mine was #5 On 1~4 Off, check remote control dip switches in 9v battery compartment also set #5 On 1~4 Off, new 9v battery still no Fan reversal "click" sound heard coming from the large Blue fan reversal relay located inside the Cp9430 receiver. All other buttons control transistors and will make no sound even if they are working.
3) Disassemble / unplug 9 wire plug from Cp9430r receiver, place receiver on wooden table, 9 wire plug has two empty pin squares, one empty in the center, the other empty we will call #1 ..counting clockwise #2,#3...#4,#5..#6,#7and finally top center next to empty #1 is #8. Now #8 is 110v hot/black ...& #4 neutral/white.
4) Shock Danger..carefully apply ac volts to pins #8,#4 use tape if needed, locate quad operational amplifier i call it radio receiver chip HA17324 on board, google HA17324 Datasheet, locate leg #14 it is across from leg #1. Locate small yellow ceramic capacitor very near leg #14, use capacitor's neg as neg for voltmeter, test volts at #1,#7,#8 and #14. My #1 was 3.1v, #7 3.2v, #8 3.25v and #14 .01v ...why #14 so low? I monitored each leg while pressing remote control buttons...no changes. **Desperate, I sparked (1/2 second or less) #14 with 3.14v from positive leg of yellow capacitor** and retested all legs, no change except now #14 rests at .02v and jumps to 2.5v~2.8v when any button on the remote is pressed then rests at .02v. Now Lights work, Fan speeds work, Reverse rotation Works :-)
Pin Out on 9 wire plug, #1 Empty pin, #2 Alternates w up/down fan rotation, #3 goes to 5uf fan capacitor other side of cap goes to white/neutral AC Line, #4 AC Line neutral, #5 goes to Triac? speeds? , #6 Alternates up/down fan rotation goes to up/dn blue relay, #7 goes to up/dn blue relay looks to be AC hot looking for fan probably paired with #3 changing sides at up/dn blue relay, #8 AC Line hot in. Why did **sparking** work, smarter people might know, i think a small spark got stuck in the chip and sparking helped the chip release it out. No electrical education, novice. Jer. 51 8,9 and 11
