Townhouse ac/heater combo won't start
I am not familiar with this air handler, but I haven't found too many with fuses. You just blow the transformer... but if you found a place that says there is a fuse, maybe there is.
If you can use a volt meter, check the voltage between the red and blue wire in the thermostat. It should be 24 volts AC. If it is there, your problem is something else... Some might suggest you use a short jumper wire from the red to the green and see if the fan comes on to check your 24 volts if you don't have a meter, but I would never suggest that...
If you determine that the 24 volts is not there then you should find that transformer in the air handler and follow the leads out and see if they lead to the fuse, if it exists. You might consider that the transformer is bad if you can't find a fuse. If able, check the primary for your supply voltage, 115 or 230 volts AC, and the secondary, 24 volts AC.
If your lucky, someone that is familiar with this model will answer with all the locations, etc...
Always be careful when working with electricity. If you decide to get into the air handler to troubleshoot your transformer, turn off the breaker while exploring and only turn it back on when you are ready to make voltage measurements and are confident that you know what you are doing.
