My AC seems to be incompatible with the rth2300 thermostat,

Customer Question

My AC seems to be incompatible with the rth2300 thermostat, it blows the 3 amp low voltage fuse. I removed the thermostat and connected a switch to connect red (hot) to green & yellow (compressor and fan) and it works fine. I've cycled several times without the fuse blowing. I tried 2 RTH2300s so it seems like it has to be the thermostat. Got a suggestion for an alternate thermostat please?

Hi i am dan I can help you with this, it is very strange for that to happen but not surprising for a honeywell thermostat. I would recommend an aprilaire or pro iaq thermostat I rarely have problems with those 2 brands. You can pick whatever model you prefer if you have just a conventional ac system.
