If you are replacing a stat simply put the colors back to the terminals they came off of. If this is a new install R= 24v control power supply from the source(usually the air handler). Y=cooling,W=heating and G=fan. Y,W & G all send control power back to the unit and their respective relays. Y will need to go to the outdoor unit along with a common,as that is the control wire for the compressor. G will go to the fan relay terminal in the air handler and W will go to the heat relay terminal for the gas valve also in the airhandler. If you have RC & RH instead of just R they can be jumped together if you have a single control power source. If you have 2 control power sources RH & W need to use one and RC,Y & G would use the other.

How do you know if your geyser thermostat is not working?
Disconnect power to geyser and remove the thermostat. Turn heat selector to maximum and with the thermostat removed from the geyser and electrical wiring, test for continuity between the input and output sides of the (L)ive side. If there is continuity the thermostat is ok and the fault may then lie with the element.

Can cross-wiring an electrical outlet cause a household fan motor to smell like it is burning?
I think by 'cross wiring' you mean reverse polarity. This means the hot wire is connected to the neutral screw and the neutral wire is connected to the hot screw. This shouldn't have any impact on an AC motor, since AC voltage already changes polarity 60 times per second.
