 |  "York Rooftop"
, posted Thu 23 Oct 09:48  
I am just getting into rooftop units repair, working on a York, M/N DM090N15P2AAA4A and was tring to find some unit specific info , as well some general rooftop info regarding the Heat / Cool / Economizer sides of the system.
In the Trade for a long long time !
Things a bit different than before !
Refrigeration still doesn't have a "d" in it does it ?

Order of operations, Economizer info - enthalpy control, circuit board trouble shooting tips, ignitor problems/solutions, trouble shooting tips on ignition module, basically what to watch for or watch out for ?

Generally speaking; refrigerant and electricty behave the same way as they do on the ground.
