The breaker for the floor is not <span class="caps">GFCI</span> protetected.</p> <p>It&#8217;s interesting that just since I wrote in the last couple of weeks, the floor tripped probably 8 times or more (just about everyother day). It has not even been that extremely cold outside.</p> <p>Joel</p> Wed, 19 Mar 2008 12:20:05 -0000 forum.warmlyyours.com:4:19:62 JoelPSU http://forum.warmlyyours.com/forums/4/topics/19 <p>I bought and installed a system in my bathroom under tile in 2004. From the beginning the system worked well but would occasionally shut off with a ground fault indicator. Flipping the unit off and on always resolves the problem and it starts heating again. The unit might go several weeks without this happening or might do it a couple of days in a row&#8212;seems to happen more often when it&#8217;s cold outside. I&#8217;ve never seen it actually shut off but suspect it happens when the unit first turns on in the morning or evening as programmed. It is very frustrating and I should have called it in when it was first installed and under warranty, but just never did. I&#8217;m thinking of installing another unit a kitchen and want to understand this problem before I move ahead with another installation.</p> <p>The original system purchased was a 17-15B-120T and a <span class="caps">TH115F</span>-120GA. all the Ohm readers were great during installation. Test #1 40.5, Test #2 42.9 and test #3 40.1</p> <p>The intermittant nature of this is confusing. Any ideas on fixing this anoying problem?</p> <p>Joel</p> Fri, 22 Feb 2008 01:03:10 -0000 forum.warmlyyours.com:4:19:41 JoelPSU http://forum.warmlyyours.com/forums/4/topics/19
