Question about Ruud UBHC Air Conditioner

Ruud achiever 90 plus gas furnace not turning on

Some time during the day/nite the system will not start heating. No fan no clicks just nothing. The only work around we've found is to cycle the power and it will work for maybe a day or two. I've checked and clean four heat detectors. We've had three or four companies in. The last and most expensive solution to date is to replace the control board. Any one with any back ground on this would be appreciated.

Remove and clean the drain trap and make sure the drain tubes are clear.
It sounds like the water may be building up in your drain lines.
Hope this helps.

I have a Ruud Achiever 90 Plus Gas Furnace with Air Conditioner. I have a new Nest Thermostat. What is the correct wiring connections on the Furnace?

A Ruud Achiever gas furnace I believe came in a two stage model for heating. What this means is that you will have a high and a low setting. Your furnace should have two wires that control the heating cycle a W1 and W2. This should correspond with the terminals on the nest thermostat. You may run into issues if you do not have enough thermostat wires to control the furnace. If you are ever in the need for Ruud And Rheem Gas Furnaces we offer a great selection online. Shop Natural Gas Furnace. We also have a chat line which can provide technical support.

The door, you mean the metal cover on the front? if you have the door off and push the safety switch in with your hand everything works fine? I need more info here, but if what I said is right, then the "door" isn't making good contact with the switch.
