Hey got a question about a Lennox RTU. Customer states the blower runs non stop. I replaced the K25 board and same thing…blower keeps running. The thermostat relay isn’t stuck nor is the contactor stuck closed. I’m going back to it tomorrow so was wondering if any of you guys have had this issue and what you did to remedy it…I don’t have the model number…I’ll grab it tomorrow. Thanks in advance.
