If not change the batteries on t-stat and try again.If it doesn't you need to check for power to furnace, and if that doesn't work you can check the doors on the furnace to see if they are tight and the door switch is engaged.A normal sequence of operation would be the induction motor comes on, after a few seconds, it will check whats called a sail switch to ensure it is venting air, at that time the glow plug should come on, and following the gas valve opens, firing the burners, the flame sensor will check to ensure that the flame did light to ensure burners light, and then the blower motor will engage. 

Lightweight and good battery life is desired over high performance.

Batteries for those pesky smoke alarms is a must

With Ca policy driving toward AB 32 objectives, Title 24 updates, solar continuing to boom, electric vehicles hitting mainstream, Tesla battery units, water concerns... seems like there are a lot of interesting elements to consider with new development.

I will need an electrician who can hook up solar and a battery pack, and a plumber who can hook up a rainwater capture system. 

Besides recharging a rechargeable battery (fast charge, no waiting), there are hydrogen fuel cells (refill the hydrogen tank with hydrogen) vying for consideration.

As to cell phones, keep the batteries charged!

Anywhere I have a sump pump I have a battery or domestic water (no well) backup.
