Check voltage at unit. Also check the 5 amp fuse in the unit. If this unit has a float switch in the drain line check that. Rus

I have a carrier debonair 250 thermostat ..2 issues 1. When I manually put the heating temp I want the flames go on.....10'sec later on ......ten sec off. Then the fan blows cold air no heat 2

This is most likely the flame sensor in the actual furnace and not the thermostat. Post the model of the furnace.

Carrier HVAC thermostat not fully displaying digital read out. Control bottoms doesn't work have to depress really hard and eventually works

Does it have a battery backup in the unit? If so replace them. If its an older model used frequently oil from your hands gets behind the buttons which causes intermittent connections and can cause display error. Remove the unit, carefully open it up and clean all contact surfaces with q-tip and a bit of rubbing alcohol. May solve your problem. While your at it make sure all wire connections are tight. Mark all wire locations during disassembly to make sure they go back in the right place.

I know it sounds simple but the batteries are probably in the wrong direction. If they are correctly installed and fresh you will usually get a display.

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...

Samsung i730 is frozen at align screen

I don't have the solution, but this is directed to "Guest" (that posted on Nov. 3, 2007.): I don't think you'd want to call Verizon because they're simply the carrier for the network. Samsung made the phone, so even though it says "Verizon Wireless" on the phone, the people you should contact would be from Samsung. Samsung would know more about the techical details of the i730, since they manufactered it. Sorry this is so long......
