Error codes for Protech/UT Board?

______________________________________________________________________ Hi folks, I have a furnace question… I have a Hamilton “Conquest 80″ that had foundered in the post hurricane flooding. I have replaced the United Technologies control board, as the blower ran constantly, with no vent fan and no error lights. Now I have vent fan, a “three blink” error, and still the constant indoor blower. The Protech replacement board is a 62-24084-82, and the documentation doesn’t give error codes, the furnace gave none for the original board either. I can’t find the error codes anywhere online. Thanks for any help at all!

I found the schematics on the door of the AC. But I could not figure the color codeing for the P3 connectors. On the left of the board you will see: Twin Y G W R C. can you tell me the color of the wires that goes to each one of these.

If not who makes the control board.

It’s made for Century, Comfort Aire, Rheem or Ruud. I’ll examine the board more closely for a silkscreen of the codes, I don’t think it’s there. Here’s where I found it: http://www.partsguy.com/cgi-bin/PartsGuy/622408482.html The furnace offers no codes, but had used a United Technologies 62-24084-01 board. Thanks for the help, it means a lot to me! xenos Webmaster “Re(3):Error codes for Protech/UT Board?” , posted Sat 9 Oct 07:39 ______________________________________________________________________ Normally if a blower runs all the time and heating does not operate, its either a blown control fuse ( NC blower relay), or an open limit. Xenos. The best way to escape a problem is to solve it.

Thanks to you guys I got the furnace to function. Starting with your clue that a control fuse, NC blower relay or open limit usually explains constant blower and no ignition, I traced the 24vac and found about 10mv in the connector back on the board. Bad connection, leaving the board thinking that the limit was open. Why is it so hard to find Rheem’s error codes? I never could find them, with hours of Google time! Thanks again! xenos Webmaster “Re(5):Error codes for Protech/UT Board?” , posted Sat 9 Oct 19:31 ______________________________________________________________________ ongradulations, Rheem is not a main line manufacture like lets say Trane, Lennox, Carrier therefore support is a lot harder to find. Xenos. The best way to escape a problem is to solve it.

I had hoped that some relays would be socketed, but they all seem to be on the board. Still trying. xryan “Re(5):Error codes for Protech/UT Board?” , posted Tue 6 Dec 22:06 ______________________________________________________________________ If you figure out the answer, let me know. I’m having the same problem and am on my second control board. I’m starting to finally figure the board probably isn’t the problem. Thx Sean DJOMCSE “Re(6):Error codes for Protech/UT Board?” , posted Thu 9 Feb 23:10 ______________________________________________________________________ Hello all! I have the same issue…constant blower and no heat. Furnace doesn’t respond to anything from the thermostat. I pulled it off the wall and the blower still kept going. The only way to turn off the blower is to remove power. Should I replace the board, or chase something else? Please help! It finally got COLD in Cleveland!!! The only good thing is that my gas bill may go down a bit! Help me when I need it and your computer will always have a friend!
