Replace the furnace control board. The board was the correct board. I wired it and went to test and nothing would work. I had line voltage and low voltage but 0 volts between r and c on the thermostat contacts. I triple checked everything and installed the old board and the unit operates. I installed it once more and replaced the fuse but still no low voltage at thermostat contacts. I called Matt and Donna to let them know. Matt to reorder the part. I have the defective part to return. Let customer know the situation and that the office would call ASAP when the part comes in. Upon arrival today I saw the igniter glowing after the furnace had stopped heating, as was described by the customer. I replaced the control board and secured wires with zip ties. I cycled the unit from the thermostat and am happy to report that the unit is operating normal.

Upon arrival I was told that main office wasn’t heating. Customer also informed me that 2/3 make up air units aren’t heating. During diagnostics I called for heat and went to roof. Found office RTU was running in ac and unit frozen up. Found thermostat wires jumped together. Wired correctly and tested system. Unit is straight ac with electric heat as primary heat. Tested electric heat and measured amp draw. Let system continue to run and found no additional problems. Went to Captive Aire units and found both blower motors were running backwards, not letting pressure switch close. Switched wires for 3 phase motors so they spun in other direction. Returned power to units and let them cycle naturally with controller. Found normal operation after rewiring. Units operating normal. Customer showed me problem areas but left site before finishing. Couldn’t get signature because I couldn’t find either contact in warehouse. Set all fresh air units for 55 heat on and 62 heat off.

The customer explained to me that on several occasions they had passed by the furnace and the igniter was glowing continuously, even though there was no call for heat and the inducer motor was off. Customer thought the igniter was the problem but I explained that the furnace control board is beginning to fault. Even though it did not do this in front of me, the customer knows the equipment and i have seen very similar problems once a short develops in the control board circuit. Customer paid for the repair in full. I completed a parts order form. A technician needs to return as soon as the part is available to replace the board.

I operated the unit on heating mode. Previously the blower speeds had to be switched so I was interested to make sure that the unit was moving the correct amount of air in heating mode. Temperature rise was within comfort range and cfm was just over 1,000. Blower speeds are set correctly. I set gas pressure to 3.5 from 3.67. I checked the electrical wiring and electrical systems, all are within specification. I replaced the filter with one provided by the customer. The unit is operating normal. Customer is waiting until the spring to add a hard start kit to the condenser unit. I will resend an estimate for this repair even though it has no impact during heating it is one of the more highly recommended repairs.
