Furnace blower won't turn on
Hi there, I have a 11 years old York Furnace that all the sudden the blower won't turn on any more. Can someone help me on this? WHen the heater is on, the burner will start, and then I can hear a few click sound at the blower section, but it won't start. The furnace shuts down after about a few minutes burning. And the next time it will flash 4 times and the panel says it mean "limit open", I have to reset all the milit switches.
Also when I put the fan to On position, the blower did not come on, and I can only hear a click sound. Normally the blower would starts right away. Is the relay, capacitor, motor or something is wrong? It was working yesterday. I can use my fingers to move the blower fan freely in both directions. I did check all the wires and seems they are all good. I checked the C and R connected and they have 24Vlot as well. Just running out of clues? Any help is much appreciated. They said tonight the Bay Area will hit record low temprature and would like to get it fixed soon. Thanks. |
