Re: york

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?

Re: york

You may already have the info you need. Look on the reverse side of the access panel on the unit. Typically they have a diagnostic schematic next to or combined with the wiring diagram. York is owned by Johnson Controls and you can contact then at 877-874-7378 if you don't find the diagnostic codes I refer to.

12 year old HE York diamond 90 furnace burners ignite for a few seconds but won't remain lit. Hot surface igniter then glows and burners again light momentarily. Cycle repeats several times before blo

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.

If your furnace uses an electrical glow element to light the pilot light, the Glow Element will need to be replaced. Glow Elements are general used on 90+ High Efficiency Gas Furnaces.

If it uses a standing pilot light rather than the Electrical Glow Element, you need to manually relight the pilot. Since I can't see your furnace, you will need to locate and read your Owners Manual on how to do this or look in the side or inside the pilot light compartment for instructions on how to light it.
Be sure you have stick match or a butane grill lighter with you before you try to light it.

If it's a manual pilot ... if after lighting it, it doesn't hold when turned to the ON position, more thank likely you'll need to have the Thermocouple replaced.

And above all, BE CAREFUL. If you don't feel comfortable lighting a gas furnace, call a professional.

You could have plugged orfices in the line coming out of the gas valve. Next you could have a plugged gas regulator.The only way your going to find this out is to check gas pressure before the gas valve during a call for heat and then check it after the gas valve during a call for heat you could have a bad gas valve. Try this let me know what you find Thanks and please leave feedback

Problems with Furnace

On is just the blower fan nothing else, check to see if there is a reset button in the tstat or tripped over load inside the furnace, inside the furance is some safetys, you will see wires runing from each other and finaly to the gas valve, push each untill one of them clicks,then your furnace should start back working, but I would still have someone come out and check why it tripped, because as I said it is a safety, and when it tripps it is for a reason.
