There is a replacement board on the market for this board that is made by ICM. I have been asked repeatedly why the Carrier replacement is more expensive. The following is cut and pasted from an email from Carrier Corp and explains the difference in the 2 boards

Thanks for the note.  We're asking because we've found out that some of our dealers are using ICM controls in our furnaces.  I must inform you that our Engineering community has reviewed the specs on ICM boards, and have determined the following issues:

  • This control has 60 second on-delay only.  If used on an 80% product it will have major HX (heat exchanger) failure issues.

 

  • Since they do not detect furnace type or backward compatibility they probably only have one post purge timing.  They may not have pre-purge or post purge at all.

 

  • The cool relay is rated for 10 amps only and ours is rated for 20 amps.

 

  • We have an unpublished internal safety algorithm that this control does not have. It relates to flame sense.

 

  • If running continuous fan or heat pump mode they may not shut the blower off when the igniter is energized.  If not this could cause nuisance circuit breaker trips.

 

  • The control has higher resistance load resistors and may have compatibility problems with some thermostats.  (Based on photo)  

 

  • The control may not shut off the HSI the moment that flame is sensed.  This will give reduced reliability on a Power Heat igniter.

 

  • When replacing one control in twinned furnaces both controls must be changed.

 

  • Carrier's flame sense software is quite extensive in regards to checking the circuitry and how it detects flame.  This control may not supply the same level of safety as their software.

 

  • These controls may not be UL or CSA listed.
