"Blower set screw"

2.0 rating
Somewhat Unsatisfied

I am a service technician and over the past couple of years I have had to change out the blower motor and wheel on two units and an entire blower assembly on another. The cause? The set screw used to secure the blower wheel to the motor shaft was too short(factory installed), by at least a 1/4 inch. The blower wheel eventually began to slip around the shaft, wearing a groove in the shaft and then the hub wallowed out and caused everything to be out of balance. The cost of repairs was an expense my customer should never have had to incur. Shame on ruud, another few pennies for the proper length set screw on their part would have saved my customers $200-$300.

"Would not recomend"

1.0 rating
Very Unsatisfied

I had this furnace installed 5 years ago and I have had the service guy here every year for five years. I was told when making my original decision that with this furnace I will never see the installer again, it is just that good. We’ll Good thing I like the guy cause I see him a lot! Main issue is the sensor carbons up. He tells me it needs to be cleaned every year. So basically I am to pay $150 a year to clean a sensor that takes them about 2 minutes to clean. Chances are it will carbon up again during the heating season. How cost effective is that? Sounds like a bad design issue.

"Garbage"

I contacted Ruud about freezing off problems, and all I received from the manufacture was: Oh well big deal duh we don’t know what to do. Every winter the Achiever plus freezes off — plugs with ice and shuts down. How does a person go any place when you cannot trust the furnace you were told was a good top of the line unit? The installer would not even come back to warranty anything so if your considering a Rudd give me a call you can have mine because I am ripping that piece of garbage out of my home, and installing a unit that can handle cold weather.

"Beware"

It would have been cheaper to burn dollar bills than fixing this thing. It is only 6 years old and I’ve put in over $1000 into it. And of course it always fails on a weekend.

"Underachiever"

1.0 rating
Very Unsatisfied

I have owned this Ruud 90 plus furnace for approximately 10+ years. I have had service on this unit approximately every other year. As I have heard before problems seem to be minimal nevertheless it keeps it from functioning properly. I live in the upper mid west where the temperature drastically changes from day to day and I cross my fingers when I have to use this unit for heat. I would not recommend this Ruud FURN/Achiever 90 Plus unit.

Other Achiever 90 Plus Reviews

Hvac-talk.com revealed a post from an owner whose flame would die out immediately. Another homeowner wrote that he had corrected a similar problem by replacing a drainage tube, which had become obstructed.

Another Ruud Achiever 90 Plus furnace owner writes to the experts at justanswer.com about the blower running, but no heat coming out of the vents. The contractor was able to discern after some discussion that the problem was probably being caused by condensation in a drainage tube once again. The expert stated this was a problem he rarely saw in many years of working on furnaces.

A homeowner writes on doityourself.com about problems with the Achiever 90 Plus not staying lit. A solution is not reached on the forum, but some responders feel the LP gas tank may need to be filled to increase the pressure.

A recent post on hvac-talk.com also mentions the issue of the burner going out. The consumer reports that the venting outside was at an incorrect angle and wind was entering the system and causing the problem.

Question and Answer

Question:

What does a green flashing light mean?

Answer:

This flashing light is indicating an error code based on the number of flashes. In your owner’s manual or on the inside of the cover panel or perhaps on the furnace itself there should be a description of how to read the code and what each code means.

Question:

The furnace wouldn’t kick on last night. The ok light flashes twice. It doesn’t try to purge or ignite. Fan works.

Answer:

Many times the air filter can be clogged and prevent airflow. If after replacing your filter your furnace continues to have issues you should hire a licensed contractor to look at the unit.

See page 2 of the manual for the location for the pressure switch on your Ruud Achiever 90 Plus. There is a picture which shows it in the middle of the unit.

Question

Where is the limit switch on the Achiever 90 Plus?

Owned 15 yrs but hardly used because we burned wood only backup and absence times. we started it this fall and began this. turn thermostat up and fan wants to start before it ignites. cleaned board and ckd what could. no service manual given when installed. think it may be limit switch.

Page two of the user manual identifies all the major interior parts. When it comes to working on a furnace I strongly recommend hiring a licensed contractor (due to the potential harm you can cause). Licensed contractors spend years in school and doing on the job training. So if you’re unsure of your abilities, contacting a contractor is always a safe bet!
