Electronic thermostat problem?

Last year I put a new Olsen hot air furnace in our house. During some trouble shooting, I was told that the newer furnaces (my new one has the LED light on the Beckett burner control) does not like the old style mercury t-stat. Apparently, they don't run quite right with the older t-stat. So, we put a non programmable electronic t-stat on the wall. In the last year approximately three or four times the furnace has quit in the middle of the night. The scenario is that the furnace runs through its cycle, but does not start back up. There's no change in the LED light, I believe that there should be a red light on if there is something wrong- no light at all is on when this happens. Turning the t-stat up or down does nothing. I have learned to turn the power switch off, wait 10-20 seconds, turn the power back on and everything comes back on A.O.K. The green LED comes on and everything works normal again. Someone said that the electronic t-stat's don't work well- or they have alot of problems- any thoughts? Thank you.

What type of electronic tstat (brand and cost) did you install. The cheap ones are troublesome and the only ones I recommend are the Honeywell Focus or Vision Pro units from HDepot. Contractors have access to better quality White Rodgers etc but the DIYer can get the Honeywell. I have had elcheapos drop the voltage and damage circuit boards. You get what you pay for.

A. Get a Honeywell Focus or Vision Pro stat.
B. Inspect your thermostat wire for splices that may not be tight.
C. If your thermostat wire is real old, run new.
D. Make sure no wire insulation is under any screws.
