Came out today for a no ac call. Upon inspection I found that the system had an error code for high pressure. I reset the high pressure switch by disconnecting the low voltage wire from the board. The system started right up and I took an amp draw for the fan motor and received a reading of 2.8. The fan is rated at a max of 2.8. This reading tells me that the fan stopped operating at some point and the system locked out on high pressure. The fan motor and fan blades (3 blade) should be replaced. Once the fan motor is replaced further diagnostics may be needed. Once the system is operating properly Chud will then perform preventative maintenance. This is a Lennox system model #sl18xp1-036-230a02, serial #5817e24244. Chud will have to call the homeowner and let them know if the repair is covered under warranty, pice if it’s not covered, part availability and repair date.
