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
