How to select correct thermostat

      My old thermostat is broken. It is a White rodgers LR27935 Class 2. I bought a Honeywell RTH2300B only to find the wiring is not compatible. The wiring is labeled A Y G RG RH W. What is compatible with this wiring? I need something I can do myself, Frozen single mom on a budget. Thanks!

Bobbie I'm the Hammer and I'm on this for you. First I'm going to need some info about your heat... is it a furnace or a heat pump, etc? I'll be looking into this with what you have given me, but the sooner you get me this information, the sooner i can help you warm up.
