SOURCE: I have a york diamond 90 diagnostic 1 flash lock

open the top of your unit so that you can see into the burner box
what your looking for should be an orange wire that leeads up to a metal rod
that metal rod should be in the way of the flame when unit is on
this is your flame ground,,, or more commonly known as the flame sensor,,, take this out and goive it a good brush with some steel wool
and reassemble,,
this should clear up you problem

SOURCE: York Diamond 80 furnace (propane conversion),

Check for 24 volts across the two terminals on the gas valve when the ignitor glows. If yes, bad gas valve or blockage in the gas train. If no, bad ignitor or circuit board. Even if the ignitor glows, it still may be bad and not sending the proper signal to the board. If you jump the R and G terminals on the circuit board, does the fan still only run for 90 seconds? If so I would say replace the board.

There may be more than 1 limit switch. Look at the wiring diagram and follow it to all switches. Or jump out the complete circuit.

The flame sensor can still be faulty, replacing that is the cheapest. Other issues could be a faulty control board (if available), a faulty gas valve, thermostat lossing call, or a safety/pressure switch problem. There are alot of variables and it really helps to have a meter to check voltage and continuity through-out the system.

The thermocouple could be defective. If this is a high efficiency York furnace, the stack blower should start and run first. If it doesn't the blower controller may have failed.

York Diamond 90 furnace blows cold air


There maybe a few issues. They have multiple safeties on furnaces. With this in mind this process to find the problem would take a Technician to check these safeties. It could be a flame sensor or thermocoupler each senses a flame or heat to keep the gas going. Also the damper for the flue must open for the gas to stay on. There may be more safeties on this and each safety sends a 24 volt current back to control module in order for the gas valve to stay open. If these aren't being met it will try around three times and go into a lock out mode which will keep gas shut off entirely.

The furnace is not sensing the flame. Turn off the power.
There is a metal rod in front of the last burner to light. It is corroded and needs to be cleaned. Its the flame sensor .
take the 1 screw out holding it in to the bar and scrub it with some steel wool till shiny. replace and turn on furnace. all should be fine.

I have an old York outside compressor/coil/fan unit, CDHF36-6A, that I need to replace as it is no longer repairable. What is the capacity of this unit and what Carrier unit would be a good replacement?
