Troubleshooting Tips (in approximate order of likelihood)
No power-on beep and/or no receiver module power LED
• Battery cable connected incorrectly
(Match “+” and “-“ on the INPUT side with your battery connector)
• Bad solder joint on voltage regulator
• Bad solder joint on 10 uF capacitors
• Bad solder joint on the processor
• Buzzer mounted backwards (long lead needs to be on the “+” side)
BTN Light doesn’t flash when I press a button on the remote
• Bad solder joint on the 2.2K resistor next to the LED
• Bad solder joint on the LED, or LED reversed
• Bad solder joint on the receiver module pads
• Solder bridge on the receiver module pads
Button press not recognized or no “click” when I hit a button
• Bad solder joint on the processor
• Bad solder joint on the receiver module pads
• Buzzer mounted backwards (long lead needs to be on the “+” side)
Switch won’t turn on when I enter the code
• Bad solder joint on the “ON” LED or LED reversed
• Bad solder joint on 4.7K resistor next to the ON LED
• Bad solder joint on the processor
• Bad solder joint on the MOSFET
• Bad solder joint on the 10K resistor next to the MOSFET
