I just bought a used bator and was told it was only used a couple of times. . Is there an easy way to test the wafer? I heard that the wafer thermostat is very reliable When the pilot light is on I hear a buzzing sound which may be the wafer thermostat right? My other Hovabator has always been quiet and has been in use for two years continuously. thanks for any help sorry to submit this post twice. i guess i have another question ? how do you delete multiple posts?
