ruud furnace problem

troubled1 · 10-17-2006, 02:31 AM

when i went to fire up my furnce this year it would not come on. it worked last year. when the thermostat is put in heat position the induced draft motor never starts. i changed out my card and i still have the same problem. i can jumper the (IDM) and make it work, but otherwise it never gets the power to kick on. does anyone know the flashcodes for for this card 62-24084-02?

Hi troubled1

On most models of Rheem/Ruud furnaces, if there is a limit open it will not do anything. Turn your thermostat to the heat mode, use a votmeter on A/C volts. Locate your limits and put one of each of your probes on either side of your limit. If you read voltage that is the limit that is open. Most are resettable, but if it is not you should be able to go to a dealer and get a new one. They will tipically range from 12-25 dollars.

Good luck and let me know if that does't work.
