It’s technically a reversing valve it just a reheat valve just re directs it I guess you can say tbh I just prefer the rack to have heat reclaim

Never fails, the more you dig the more you’ll find wrong. This unit has probably never worked right and probably has seen little maintenance or someone would have caught this.

Can you share what an average bill looks like? For example working on this unit? Thanks.

Lennox parts quality has taken a dip. Especially when they started using there own inter link brand. You lost the relay from a lock rotor amp condition from the failed run capacitor. Most likely from overheat them cheap sleeve bearing motors are Knacked. Cooks the oil out of the wicking. I would ohm out them motors and check for endplay. Also would recommend getting a uF meter to test caps out of circuit. One last watch out for TPO roof slime!
