I have a 14 Year Old Carrier 58MVP Infinity Furnace. I know the hot surface ignitor is defective. It is behind the inducer motor. Is this something a novice like me can change. I already bought the part ($27.00) and want to do it myself because the contractor wanted$220 for the fix which seemed exorbitant for a \$27 part. However, maybe it is not out of line. Any help on how to do this (or if I should uattempt this) would be greatly helpful. I have changed surface ignitors in larger furnaces that were readily accessible, but this seems to require the removal of the inducer fan. Is this correct? Your help would be greatly appreciated.
