I have an M1MC 070 A BW furnace and it has a flashing red light. The light is flashing 4 times which from the table on the front of the machine means that it is "lock out due to failed ignition". I'm wanting to know if there is an easy fix to this or if I need to replace the igniter. It gets flame, the blower comes on but there is no heat. If someone could let me know I would really appreciate it!

Hi,

When you say it gets flame, do you mean the ignitor glows and the burner does ignite ?


However, you do not get heat from the registers ?


Is the airflow good and strong/normal from registers though not warm ?



Thanks,
Robert
