No buzzer intermittently - JC

Hello: I’m experiencing an intermittent issue with the Coleman system’s buzzer/chime—no chime when dropping tokens or coins (most noticeable in the morning). Power-cycling temporarily brings the chime back, but at a low volume; other times it works normally. All other functions appear normal. I have a Dixmor LED6 timer on this, a pretty new one.

My first step is to replace the speaker. Before I proceed, do you have any other recommendations?

Thanks

replace speaker

Swap the the Dixmor timer with another bay and see if the problem goes with the timer. If it does send the timer to Dixmor for repair. If the problem stays at the bay replace the horn
