Hey there, sorry to hear you’re having trouble with your Gentex WGEC24-75WR. It’s a common issue with these devices. Firstly, ensure that the power supply is stable and that the wiring connections are secure. Sometimes, loose connections can cause erratic behavior. If that doesn’t solve the problem, try resetting the device by disconnecting it from power for a few minutes and then reconnecting it. If the issue persists, it might be a fault with the device itself, in which case contacting Gentex support for further assistance would be advisable. Let us know if you need any further help!
