Yesterday I received a call from cousin of mine asking about replacement costs of a furnace. Seems that some friends of his and his wife's had to call in for service as their furnace wasn't working. I service guy came in on Saturday morning, spent 20 minutes looking at their furnace. Told the homeowners that the blower motor and ignition control module had failed and they they needed a new furnace! I couldn't believe it so I went to give a 2nd opinion. As the initial tech stated the blower and ICM had failed but I found no reason to replace. I did notice that once while the unit fired it did backfire, for lack of a better term. Almost like delayed ignition but several minutes into a heat cycle. I will replace the blower and ICM tomorrow but has anyone had any experience with the Quatro line? I o know it is made by Consolidated.
