    Help- stumped! Control board, limit switch, or something else??

    I agree, definitely install a carbon monoxide detector in the basement near the furnace. And ... since the temp rise is right, a cracked heat exchanger is unlikely ... although always possible. But ... a cracked heat exchanger would not explain the negative pressure in the basement. That's...

    AC condensation drain blocked, water overflowing

    It is a terrible design. Terrible enough that if it were my house, I'd move the ac air handler out of the attic, down into some sort of alcove in the living space. Still better, install a new, clean air handler, with a MERV 8 or better "media" filter setup. What you're experiencing is the...

    Quatrix, I'm not a licensed electrician, but I feel that the above answers are a pretty clear ... "no".

    Noise thru heat vents

    In that mild Berkeley climate, you might consider just installing mini-split ductless units in each living area. Remove all of the central heat / air equipment, and whatever ductwork can be reached. Especially if you're in that house for the long haul. These days, the mini-splits are pretty...

    It's cold upstairs

    If your upstairs bedroom is only 1 degree different from the 1st floor, your system is balanced pretty well.

    New thermostat for gas furnace.

    everything pjones said, hire someone to install the new thermostat, I can tell from your post, that you're not skilled enough to do it. Get help.

    Amana RCE36C2C condensor fan runs slowly with AC off

    I have to admit, it's a mystery to me. What you've described is a situation I've not seen before.

    Help- stumped! Control board, limit switch, or something else??

    The furnace working ok for several days after you opened the basement window 3" is good information. But .. sounds like there is still negative pressure in the basement, even with that window open 3". 2 possibilities come to my mind .. 1. the return duct in the basement, is somehow pulling a...

    Help- stumped! Control board, limit switch, or something else??

    A medium-efficiency (around 80%) furnace also has an inducer motor/blower (combustion air fan), although those furnaces are not condensing furnaces. Normally, the flue exhaust gases will be warmer than a condensing furnace ... about 220 degrees F. This is enough to trip the temperature sensors...

    Help- stumped! Control board, limit switch, or something else??

    I would replace the limit switches first. They're not expensive. I think Carrier boards are not cheap, even wholesale. Could be an online source of a compatible board, not sure though. If the switches don't solve the problem, my guess is that the board has just gone a little crazy, or has been...

    Amana RCE36C2C condensor fan runs slowly with AC off

    yes, in my work there were many times that the hipot (for high potential, which means voltage) meter would pick up a winding short to ground, that the Fluke multimeter could not. I think the winding shorts like that, are mainly due to weaknesses in the insulation on the windings. The weaknesses...

    Amana RCE36C2C condensor fan runs slowly with AC off

    you wrote ... After doing some reading online I realize it may be only one leg of the 220V is switched, so a winding short to ground could allow some power through the motor. In my experience, this is what you have going on. Not always true, but I've seen it a lot. To confirm it, a...

    Emergency boiler replacement - some Qs from a newb (long, sorry!)

    I don't like that about propane either, that tank. A bud of mine installed a 1000 gallon underground tank, I'm thinking he might own it. Probably pricey to do, though. I have to admit, being able to get oil from any supplier is pretty good.

    You are welcome, I wish you and your family all the best.

    Emergency boiler replacement - some Qs from a newb (long, sorry!)

    This is a good opportunity to remove the boiler system, and install a forced-air propane system, or natural-gas if that's available in your area. With that you get air filtration, and the difficulties of oil would be gone. 1600 sq ft isn't a big house, and a centrally-located furnace-with-ac...

    VR8204c3007 natural gas valve buzzing

    I'd say replace. I'm in the camp that says ... "you've been warned and graciously given time to deal with it". If it were a boiler in Gainesville Florida, I'd wait until it died. Not in Minnesota though.

    Heating question

    lol about the hammer idea .... ;) always use one at least 2 lbs tho. Those pump motors are so quiet, it will be hard to tell if it's running. If it's not, the motor's dead or the sensing device that turns it on has failed, or a wire has come loose, or a wire connection is bad. If it's running...

    VR8204c3007 natural gas valve buzzing

    I'd be preventative and get it replaced. It's a critical item, and you're in a brutal winter area. It's probably just the internal valve's coil buzzing, but it shouldn't make any sound. It's not actually a warning buzzer, but I'd treat it like it is.

    Replace whole unit or nah?

    A 2007 heat pump is near the end of its designed life span, since a heat pump operates year round. $1000 to replace a TXV is a bit high. I'd go with Trane, Carrier ... well-known brands, made in the USA. I'm not really keen on Goodman .. They're ok for the price, but can be a bit troublesome...

    AC Shuts Off When it’s Hot Outside

    Awesome replies. A reset switch that's tripping usually is sensing too much current flow. In an old unit, where all the usual causes of that have been addressed, a compressor motor that's partially-shorted (due to too many powerline surges over the years) is a strong possibility...
