I have a ceiling box with two whites, two blacks and two reds. I have a light fixture with 2 wires. I attached one from the fixture to the two whites from the box then the other wire from the fixture to the two blacks from the box. The light works but I cannot turn it off? Should I be connecting...

Hi all: I recently installed under cabinet lighting in my kitchen. I added a single pole switch to an existing GFCI outlet, and then wired said switch to a surface mounted receptacle on top of my cabinets. I wired everything up, and the lights work great. The problem: When I turn...

I added lights and outlets to my basement and all of the outlets work fine. Before I started the switch on the wall controlled one light and all of the others had pull strings. I've tried everything but the switch will not turn off the remaining three lights. What did I do wrong... how do I fix it?...

I replaced my thermastat (aprilaire) with a LUX TX1500E. The furnace will not turn on unless I physically flip the switch.. It worked fine last night, however, this morning the furnace will not turn on.

My furnace doesn't comes on till I turn switch off then on
