Heating syste on central air unit will not shut off t-stat has been replaced. Disconnected power for unit and check relays in system have one relay that is operates fan and another that that routes power to fan really and to heater coil both had continuity until I disconnect power wire coming to fan relay on contact 1 and that really now is good across all contacts. The main relay showed continuity through contact positions starte to disconnect the wiring from really and upper body of relay came off in hand. Think tis is the problem any advice would be apperciated.
