Our Model is a 58MCB120 11120

SN 3107A00073 7A432-30

This morning it stopped producing heat (has gas but will not fire). The trouble light is flashing the following sequence: 3 stead flashes, then a pause, then three more steady flashes then a pause...over and over.

We cannot identify the problem...Perhaps the igniter?:

if so, where and how can we get one? I have an HVAC technician on staff ready to perform the repair. I appreciate your urgent help...It's Cold!

Here is a link to the Service and Maintenance manual for the Carrier 58MCB. The link takes you to the specific page which refers to the codes you mentioned. I am not a contractor so I cannot advice on where to proceed from there. The HVAC tech you have on staff would be a great person to show this to :)
