Fire is never normal. In your case the most likely cause is a big short in the control board of the AC unit that has dumped a lot of current in the thermostats.
This is a major fault, you will have to completely dismantle the entire system, even the wires from the walls will have to be replaced - if the current has been so great to set fire to the thermostat then it has surely been great enough to melt the insulation of the wires, turning them into fire starters - otherwise the first time you try to start it it will set your house on fire. Cut the power from the mains and call a repair company immediately, this isn't something to wait about.

    Air conditioning unit - device used to change the temperature in the house. If your heater is combined with a cooler (which is normally the case) then it's called an air conditioner. So the problem remains the same : the thermostat has been fried by a faulty control board, fix all of that.

    Baseboard heater = simple electrical heater - just a resistance. It's almost never used alone as it's the worst kind of heating element - it has the lowest heat generated to energy consumed ratio.Because of that it's always paired with another heater and used only temporary. So yes, i know. Check the board from the heater that is controlling it.

    If by some freak of nature you are using it as your only means of heating (in that case you must be rich since you can pay that electricity bill) then the baseboard heater is shorted and it has in turn shorted the thermostat. Replace them both.

My Honeywell programmable thermostat's display is blank and I do not have any heat?

The thermostat, depending on the model, normally does not get powered by batteries, they are for backup power. You might be losing 24 volt from the furnace, causing the thermostat to run on batteries.

Honeywell thermostat

Honeywell has made a huge number of thermostats over the years. Directions for each are specific to each model. Your model number will begin with the letters, T, TH, RTH, C, or CT and is on the back of the thermostat.
Once you have the model number, you can obtain the owner & programming information by supplying it on the Honeywell webpage, here.
If you are having trouble, either contact Honeywell directly - or repost here.
Good luck!

If you are unsure about which wire goes where, that may be the source of your problem. The color coding can be confusing when changing from old to new. I pulled the instructions for my Honeywell CT3400A thermostat and found you can call Honeywell Consumer Services at 1-800-468-1502 M-F 7:30 am to 5 pm CT

Furnace shutting on and off every four to five minutes all day

Have you had furnace cleaned? Have you changed filter or took filter out and try heater? Have you checked return grill to make sure you don't have anything in front of it. Return grill or duct could be blocked or two small. Blower motor could be going off on thermal overload. Does the heater do the same thing when it is 20 degrees outside. The other thing it could be is furnace is not big enough.
Good luck let me know what you find out
