Top Quality And Affordable A/C Repair In Franklin Park, NJ

Right On Air Conditioning And Heating performed an AC repair on Sapphire Lane in Franklin Park, NJ after a homeowner called about no air flow coming from the vents. We responded the same day to get the system checked quickly and reduce the time the customer went without cooling.

On arrival we started with a standard diagnostic and noted the system was displaying a six flash error code. On this make and model a six flash indicates a reverse polarity or grounding problem, so we focused our troubleshooting on the blower motor circuit and the control board grounding path.

To isolate the issue we applied direct power to the blower motor to confirm the motor itself would operate. The blower ran when powered directly, which told us the motor was functional and pointed toward an electrical issue upstream. That narrowed the problem to the control board or its connections.

Further inspection revealed the control board had a direct short to ground. There was a visible burn mark on the back of the control board and corresponding damage where the board contacted the mounting panel. These signs matched the six flash error code and explained why no air flow was coming through the vents. We documented the damage with photos on site.

Because the board was clearly failed, we sourced a replacement OEM control board locally and picked it up the same day. Using an exact OEM replacement ensured proper fit and compatibility with the existing system controls. We removed the faulty board carefully, noting connector locations to maintain correct wiring during the swap.

After installing the new control board we reconnected the system and performed a full start test. We verified blower operation under normal control, confirmed the error code was cleared, and walked through system controls to make sure all functions responded correctly. We also checked surrounding components and wiring for any signs of additional damage or potential issues.

The immediate result was restored air flow and normal system operation, with the control board no longer shorting to ground. Performing the diagnostics, same-day replacement, and comprehensive testing allowed us to return the system to service quickly while minimizing risk of further electrical damage.
