We have had the Achiever 90 Plus for 4 years. It has not worked properly after the first year. We can not leave overnight during the winter because you never know if it will work or not. The installing contractor is now blowing me off and not responding to messages. From most of the other reviews that I have read, it seems like a class action lawsuit may be in order.

Had a Rudd Achiever 90 Plus with dual comfort control installed in Feb 06 and have had nothing but grief with this furnace. First service call Mar 06, 2 service calls in the winter of 07 and just called again Dec 08. This furnace will not keep running, comes on for 10 secs then shuts down then comes on after about 1 min then continues this cycle. The company that installed it says they need to come and clean the furnace every year or the warranty is void. What a crock. They want $75.00 every time they come out. We have owned several homes and have had 2 furnaces replaced before and never once had to call for service even on the furnaces we did not replace. I will never buy another Rudd product. We saved over $200 on our heating bill every year but paying $150 on service calls doesn’t add up to much savings.

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.

Question

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!
