Hi everyone,
Just wanted to query the collective wisdom out there. Today, SDGE came and replaced our traditional meter with a “Smart” meter. This required a scheduled power outage. I do not know how long it lasted.
Since returning home today, our HVAC “blower” is running, and it won’t shut off. [It sounds like a fan is blowing, but the air being blown is the ambient temperature.]
We have a Honeywell thermostat, and the blower is running whether the “Fan” is switched to “on” or to “auto.”
I’ve now read a bunch of DIY/ HVAC forums on the topic, and it is not necessarily an easy fix. It may have something with the equipment that regulates the blower, or a safety mechanism that has been activated. It seems that a lot of the DIY forums assume electrical/wiring system knowledge that neither me nor my husband feels quite comfortable with.
1. Anyone with HVAC knowledge have any ideas about what to do next?
2. If we have to call an HVAC expert out here to take a look, would SDGE be in any way obligated to help pay for it (seeing as the problem started immediately after their scheduled power outage)?
Check if the HVAC setting is set to heat or cool, and if either is triggered. If fan is auto or on would be the same if the system has triggered for cooling. If cool, the fuses on the compressor for the condenser may have blown. The blower works off of the temperature in the furnace-heat exchanger when using heat. When in AC, it generally runs off of the relay voltage used to start the compressor.
NOTE: What model of Honeywell thermostat? Make sure you check the heat/cool settings noted above…
You might have a blown fuse. I recommend you turn the AC on. Check if there’s cool air. Alternatively, check the compressor(?) unit in your yard and see if the fan is running. If either or both tests fail then chances are the fuse is blown. If that’s the case you can go to a home improvement store and get a new one for about $10.
[quote=desmond]Turn the unit off by throwing the breaker switch at the electrical box to stop the blower. Then turn it back on, that may fix it.[/quote]
That’s what I’d do, throw the breaker, let it sit a few minutes and then turn it back on.
If that doesn’t work, call an HVAC guy.
Replacing the smart meter is just a power outage, nothing more. I really hate the new smart meters, not easy at all to see how much energy you’re using at the moment. It does have a little flashing two boxes and a arrow but not nearly as simple as watching the dial spin. The website is always 24 hours behind.
When SC Edison placed the “Smart” meter on my rental the bill for the following month was nearly 4 times higher than it had been before. I complained but got nowhere.
I don’t know guys. But I think the “What an excellent tap & die set for DIY vehcile repairs” spammers did a pretty good job secretly posting an off topic with a spammy link in there… I don’t think most of the posters on that thread realized it…
My husband crawled up into the attic the next day and unplugged the furnace, and then plugged it back in. Problem solved! Too bad I spent about 2 hrs doing online research trying to figure it out. Thanks to everyone (except le spammer) for your suggestions!
