it runs, pulls down to 46, shuts off, stays off for 10 or 20 minutes, warms up
to 48 or 50, comes back on, pulls back down to 46, shuts off for 20 or 30
minutes, warms up to 48 or 50, comes back on, pulls down to 46, shuts off,
stays off for 10 or 20 minutes, warms up to 48 or 50, comes back on.... you get
the point.
if it's not shutting off...ever... and only getting to 46, there's another problem.
