Hi Carrier Furnace Error code 15?
 

I have a Carrier 58mvb furnace. The error code that keeps coming up is 15, which is "Blower Motor Lockout". If i shut of the main power switch then turn back on the unit will then work., It happens about once a day for the past week. Any ideas. Thanks

It should explain more on that code. I had not seen a code just saying blower lock out. It maybe limit open blower runs all the time. That can be the furnace is getting to hot and blower staying on to cool off limit. Can take 3 hours to reset. You may need look at filter and maybe indoor coil. But start with filter. I also maybe with power off and feel the motor temp. If its really hot then you may have a blower motor problem
