Question about Ruud UAKA048 Air Conditioner
My ruud air conditioner urka-a048jk103 board is flashing 3 times now it is 2 times. The blower comes on for pre heat part and stays on. After messing around with trying to clear the line for the negative pressure control it was turning on the gas and staying lit for about 10 seconds and then turning off the gas. Then I blew to had on the negative pressure control line and probably blew out the diaphragm.. What doe the code mean.

This may be as simple switching the thermostat to electric, under the cover is a gas/electric dip switch. Hope that helps.

Rather than have him replace the control board first, ask him to remove all the freon and weigh it. He then can reuse the Freon that came out of your system put back in at the exact charge that the rating plate calls for. He will add a bit more to compensate for any length of refrigerant lines from the outside unit to the inside unit. Now this will bring us to factory specs. If the unit continues to act up, then try another board. I am not a big fan of replacing parts unless other alternative ways have been tried. If he is not willing to try what you ask, why is he there? As far as if something is taking out the control board, have him clean and reconnect all ground connections and inspect the thermostat connections both on the inside unit and the outside unit. Is lightning a factor in your area?
