for Lewis Center, OH
Was shown to furnace. Unit was giving a code for open limit switch. Used meter to verify tripped safety. Checked condition of 16x25x1 filter. Filter was completely plugged. Temporarily removed filter t measured temp rise across heat exchanger. Did notice inducer assembly operating loudly,but not enough to cause a fault for the pressure switch.
