that click could be a couple of things but try this first as it is free...... Shut off the refrigerator
if it is on propane
and see if the clicking stops. The little flame inside might keep blowing out in the wind (or air in the lines from the tank not being purged) and when it relights you will hear the click..... If that doesn't do it time the clicks to see if it's at constant intervals....if so then i would head to the converter and see if a circuit is tripping then resetting itself... or maybe the furnace
thermostat is clicking on off at the given temperature you got set even though you have the furnace
in the off position or the furnace
is on and the the pilot light
keeps going out..... just a couple of hunches but give them a try before going on to something else.
