Air handler's blower motor will not shut off
Comments (2)Sounds like you moved your speed wire to a terminal that is hot all the time did you move the wire at the motor or on your pc board or relay if you tell me exactly which wire you moved and where I may be able to help Here is a link that might be useful: Air Conditioning Repair made Easy...See MoreBTUs and blower motor
Comments (5)The correct way to determine the size of the furnace is to do a load calcualtion. Has any of the four contractors done this? Guessing or using rules of thumb are not advisable. I assume your current furnace was a 80% efficiency model. So if the input was 90,000BTU, then the output was aabout 72,000 BTU. This is a reasonable size for house your size. If you get a 95% efficiency model, then you only need a input of 75,000 BTU to maintain the same output you currently have. I don't understand the comment that a variable speed furnace will cycle on and off. Variable speed furnaces are designed not to do this. You need to address the air flow issue on the second story. You can buy the best furnace on the market but it will never work well if there are duct issues....See Moremeasuring blower motor current
Comments (4)Thanks for the suggestions. A little more background: there is no A/C use. Several fans manage internal and external air. The one I suspect typically runs 8 hours/day and *should* use about 6-7 KWH/day. I'm seeing about a 5-10% increase over my normal 18-19 KWH/day (total for the house- not exactly "skyrocketing"). The motor housing is not too hot to touch when the fan is running but its in the airstream. When the fan turns off, the housing gets pretty hot for awhile as it dissipates heat. I could measure the daily consumption with and without using the fan but there are downsides to this (inaccurate, uncomfortable)....See MoreBlower Motor in ac unit
