The York Deluxe Diamond 80 is a two-stage variable speed furnace with an eighty percent AFUE rating. The Deluxe Diamond 80 comes in two-stage Upflow/Horizontal and Downflow Models. It has an insulated blower for quiet operation and a timed-on and adjustable-off blower. The heat exchanger is made of aluminized steel to prevent corrosion.
Blower fan, control board, CFM board, gas valve, inducer motor, and other stuff… all things that have failed on this useless, garbage, hopeless furnace. It’s old… hopefully not available anymore if it is free… stay away from it!!!!
"Great and cool"
Great Machine, great install contractor. No mess, very professional. Recommend to anyone that asks.
"York Forced Air Furnace Manufacturer Defect"
Purchased a York Deluxe Diamond 80 Furnace in 2003. The weld on the blower bracket has failed on two seprate blower units in the middle of winter in the last 5 years. Repair people said the unit is notorious for this. Stay away
Other Deluxe Diamond 80 Reviews
A thread on the doityourself.com forum shows that several consumers have experienced problems with the control board and ignition system on the York Deluxe Diamond 80. They report the control board flashes and that they need to manually light the furnace. Experts recommended consulting a certified York technician if possible to see if a new control board is needed and to wire it properly.
And an owner of the Deluxe Diamond 80 on hvac-talk.com expresses satisfaction with his York Diamond 80 furnace and wants to upgrade to a Deluxe Diamond 80 for two-stage performance.
Askmehelpdesk.com lists a number of posts of customers also complaining of the furnace blowing only cold air. The answer to the cold air problem appeared to be replacing the flame sensor and igniter.
