Brrr... It must be time to check this.
This is a relatively easy replacement.
What kind do you have now, dial, electronic w/ LED/LCD readout?

No matter, we can change out either. (Note): If you live somewhere that the power co. will replace and install it, like Las Vegas, sometimes free! Have them do it, they normally will ask you if they can also install a power saver that shuts off the air conditioner during the summer. See Photo 1A↓
Ask about this. Call them, it can't hurt.
1st, We'll start with the easy one. LED/LCD readout.
I would suggest getting an LED-LCD readout to save some energy, (aka: electric bill). Most likely the one you have isn't working properly or you just want to upgrade. Look at the existing one to see where the screws that attach it to the wall are.

Usually under the plastic cover, or under the dial. You'll need to pop this off to get underneath. There might be a small prong type thing attaching the front-plate to the back-plate.

Be careful not to break the prongs, pull out slow and easy. Next remove the battery (if it has one). See the wires or a little black rectangular box? Good, Now we're ready for removal.
Unscrew it to detach the plate from the wall, you will see wires on the backside that are color coded. You might need to loosen the little screws See Photo4↓
and insert the wires from the backside of the wall plate. Match these wires to the new one you have in hand. Y,C,R,G,W,O. Disconnect the wires from existing and connect the wires to the new one, This process should be the same with either the led, or old rotary dial type, (when was your house built)? Some will require you to unscrew the little screws on the front part of the back-plate to install the wires (from the back side). See Photo 4→
Re-tighten the screws, I suggest you do one screw at a time to hold each in place. They should be relatively the same or the little book that came with it will show you the diagram for connection. Now screw it back on the wall using the existing holes. Pretty simple, huh? Now comes the fun part of setting the new one.
