troubleshooting 4 flashs indicating unfastened high limit device. Can this be repaired by myself or do I desideratum a professional to do this? Will this cost a lot of money to repair? American Standard Manumission 80 furnace.

Your furnace has more than one limit switches. These are safe keeping controls designed to open up the ignition edge in the event of overheating. Something is causing the furnace to overheat. For the DYI, I would put forward you check the filter and the vent to see if either is restricted. You will necessity to power down the furnace to reset the fault condition. Skin of that, call a licensed technician. The cost to repair this should be sort of modest.

I have a 2 year old licence 80 furnace. never had a problem until today. It starts to run for about 30 seconds. I consider burner start to ignite then shut off. LED is flashing on-off continuously at about the anyway your cursor flashes on your computer, the manual says this is orthodox "cal for heat". Any help would be greatly appreciated. Cold-hearted in Woodstock!!!

Sounds like prototypical flame sensor failure to me.

Could just be grungy (specially if you use propane), but this is in the realm of the more experienced DIYer.

It is also unpromising your hardware atore will have a replacement. Time to call someone.

P.S. It would be a benign time for a full service and clean while the tech is there. A appropriate service would include checking the sensor for develop-up anyway.
