Check for reduced air flow both return air filter (if equipped) and supply vents, make sure the flue is clear and heat exchanger is not cracked, the limits will go bad, but wont hide a bad exchanger if replaced.

Check for continuity through all your switches. Check voltage where these switches hook up to your control ignition box.if you see voltage there the problem is either the wiring or one of your switches is open. If you read no voltage there check again from "C" to the same wires a readign then indicates a bad board. Then check "R" to there a reading here indicates a bad thermostat (which is probably not your trouble due to the code and your legend of the code 4)

Hope this is cleaR and helps Please grade am accordingly and good luck.

i hope the heater doesnt come on when a limit switch is open,you really have problems. so a limit is telling you that your furnace it over heating. first check filter and heat vents and returns they must be clean and open. closing heat vent or blocked returns will cause over heating. after chacking this look at firing rate. furnace could be overfired. you would need a "u" gauge to check manifold pressure. your name plate will tell you what this should be. find the tap on the burner manifold or outlet of gas valve. fire furnace and see what it is. 3.5"wc for nat and 10" wc for propane maybe.

Limit switches are safeties and require a manual reset. They are also a Normally Closed contact. A hi temp. thermostat operates on its own. If you are sure it is a limit, find the red little button and listen for it to click. Sometimes they push pretty hard.

I have a Coleman Evcon Mdl DGAT070BDD I am getting a trouble code 4 Flashes, which means Limit is Cycling. I replace both the control board and the limit switch, and still have the same problem.


Your heater is listed under a safety/inspection recall notice, these units have been found to overheat in certain circumstances, which can lead to a failure of the heat exchanger and the furnace. Might be the cause of your problems: http://www.dgatprogram.com/ They should do a free inspection, Good luck
