Coleman DGAA090bd
Coleman DGAA090BDTB light was flashing indicating an open limiter switch. The lower switch is good. The fan would run but no heat. The upper limit switch had to be reset. After resetting it, the unit will lightly hum, but the fan will now not run.
Any idea what else I can check. I do not think I should allow the unit to hum for longer than a minute or so. Am I correct? |
