It sounds like it will need a hot surface igniter. This is the part that glows when furnace is turned on, and tells gas valve to release gas for it to ignite. At that point funace is lit, it heats up flame sensor witch inturn tells fan to start.

My ruud achiever 90 plus furnace wont run. thermostat shows system on, seems ok but furnace itself wont run. system has power.I can hear the power come on when I depress the access panel switch and also...


See if you can locate the control board. There should be an automotive push in fuse on it. It should be a small amp fuse around 3-5 amps. Check it and change if needed. You should be able to see if it is blown or not just by looking if you don't have access to a multi-meter.
The control board is usually located in the blower compartment. Thank you.

Ruud 90 Plus Achiever furnace starts, ignites, runs for 30 seconds, goes out, then does it again and again.


Hi,
It would seem as though you have a bad flame sensor or the ground from the burner to the ignition control is bad...

Could be the ignition control also but not nearly as likely...

Pressure switch can also cause these problems...

Bottom line is that you will need to grab a meter and try to figure out what is causing the flame to cutout...

Here is a tip that will help you try to figure out why your furnace is not working.

I have a ruud 90 plus achiever gas horizontal furnace. the unit will run once i turn the thermostat off then on. it will cycle a few times go off and then will not come on. any suggestions?


Sounds like it could be a dirty or bad flame sensor.
When the burner lights ,there is a flame sensor in the flame and it is suppose to sense the flame and send a signal back to the control board which will keep the gas valve open, if it gets dirty or is bad it doesn't send the signal back to the board and the board will shut the gas valve off and after three tries it will lock out the furnace and you have to reset it to get it to work again.
The flame sensor looks like a wire and it's in the flame usually it will get gas deposits on it, then it won't work.
You can clean this sensor with an extra fine piece of steel wool, but before you attempt to do this DISCONNECT ALL POWER TO THE FURNACE.

LP Ruud furnace achiever 90+. Strange problem.


Sounds like two problems. Not enough combustion air or a defective high temperature limit switch. You enclosure may not be getting enough outside air to properly sustain combustion. If the unit has a rollout thermostat it may be defective and stopping everything.

My Ruud Achiever 90 Plus not blowing cooled air


Look on the condensor, (outdoor unit) at the very bottom of the rear panel and you should find a red reset button. push it. If that does not solve the problem, and the outdoor unit is running (make sure both the fan AND the compressor are running) then you are looking at a low refridgerant issue and possibly dirty coils.

In that case, clean the coils and have refridgerant added.

Ruud heater will not light consistently


Your furnace is going into a lockout condition, cycling the power resets the circuit board and it starts over. I will need to know approximate age and model of your furnace, it sounds like you have need to clean the flame sensor rod. However i need to know what i am working with.

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.

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.
