Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

This can be caused by several things. Low input DC voltage or low LP pressure at the tank regulator or a bad control board. Do the easy ones first, like the DC voltage check with a small digital multimeter like you can find at most hardware stores for about $20. Easy to use. Most shops can check and adjust the LP pressure at the tank regulator if you remove it and take it into them. A new one is about $40 or so if you have dual tanks. You want to see about 13.7 VDC at the batteries. Slightly less at the furnace. If this is the OEM motor it may be about done and need replacing. Let me know what you find and we can go from there once you rule those things out. All follow ups are included in our fee.
