Just had same issue. should be an easy fix. take the two leads of the speaker mounted on the gold line
door. Touch a GOOD 9 volt battery to the speaker terminals. If the speaker is good....you will here some crackling from the speaker. likely the speaker is bad. you might find a cheap temprorary speaker at a radio shack type store...i had no luck at my shack. i got the speaker from "divers supply" about 15.00 each, i guess
hamilton has them too...but i just searched the model #....get a good one the cheap one i got first for 3.00 sounded bad. good luck
