I have a 4 year old Janitrol, and it has had
3 controller cards already. The initial furnace
man developed back trouble and couldn't come
do the first repair, so the company sent another
firm. They refused to honor the warranty because
they didn't issue it. So I've purchased a $300
card 3 times. And this last week, the rapid cycling
and no heat began all over again.
I think the fix is simple, but expensive.
Don't buy Janitrol.
