Happijac bed is making a pippin sound on descent.
Hi everyone. Out happijac beds have been working perfectly for the past month. On our trip this weekend, the bunks started making a loud popping sound while going down. Going up, they do not make a sound. Other than the sound, the beds are mechanically working fine. The sound seems to be right on at every three seconds, which leads me to believe it is coming from something rotating and striking something at three second intervals coming down, not going up.
I'm going home tonight to try to isolate where the sound may be coming from.
Does anyone have any ideas?
Thanks in advance...
