My miller home furnace MMHA-077ABHR-02 has a UT Electronic Controls 1018 series hot surface ignitor that is repeatedly flashing 3 times. Furnace goes through the cycle for starting, solonoid for gas opens momentarily and shuts right back off, and furnace will not light.

Next. You might try and cleaning the flame rod with steel wool.
If all else fails call for service.

On the other side of your burners is a flame sensor take it our and clean it with some emory or light sand paper wipe it off good and replace it.. the unit should work fine after that . If its not reading the flame is auto shuts off after about 3 to 5 seconds..
