Furnace not working...
Won't turn on.
Opened front panel. LED status light flashes 3 times, then pauses and repeats.
Googled it, but haven't found anything useful.

You should have a set of short flashes followed by a set of long flashes as described on page 13 to tell you the problem. The troubleshooting page will also be located on one of the doors of your furnace.

Don't have a meter and wouldn't know what to do with it.pootza wrote: ↑Dec 8th, 2018 9:07 pmThe way to check your pressure switch is with a meter. Disconnect the two wires going to it and before the purge blower turns on you should not have continuity between the terminals on the switch. When the purge blower starts that will close the switch so you should have continuity. If that's not the case give the pressure switch a rap with the plastic end of a screwdriver and try again. This may free up the stuck contacts.

And the motor is dead. Need to replace it, but the furnace installed in 2001.

We're at the 16 year mark with our carrier 58msa080. Never had any issues until last night.Enlgma wrote: ↑Dec 9th, 2018 7:10 pmReplacement depends on the age of the furnace, At $500, if the furnace otherwise has not been problematic and is less than ten years old, I'd go for the repair. Good furnaces should last 15 to 20 years.
That said, my Carrier-built Payne died six months ago at the ten year mark. After looking up information online, I tracked the fault 'flashes" to the high temp sensor in the flame box being tripped. The cause was a failed secondary heat exchanger. After a lot more research, I discovered there was a class action that had been launched and that Carrier had extended the warranty on the problematic heat exchanger to 20 years through a service bulletin according to the terms of the settlement to the lawsuit.
Getting the warranty work done was another matter. Most companies would not do it or they tried to get me to buy a new furnace. The ones who would fix the furnace wanted an extra $800 for labour over and above the Carrier compensation - reputedly because they needed 10 hours to do the work and Carrier only paid for three. Finally got a company come over to do the service work on condition I pay for extra labour. The tech came, changed the part in 2.5 hours and left. Five months later, the company sent a bill for $800 which I refused to pay based on the fact that the $800 was for seven hours of labour that had not been performed. I wrote a polite letter referencing relevant documents and the terms of the service bulletin from which they were compensated explaining my position and request that they write off this bill. They sent the bill over to collections and I got a couple of calls but they ceased after the second one. Probably didn't take it to small claims because they knew they couldn't win given the information I had collected and presented to them.
Bottom line, I got the furnace fixed and it cost nothing. It is running just fine right now.

Well, If you can get a few more years out of the furnace, I'd go with the repair. The repair guy can give you an opinion on the condition of your furnace and if you could get another five years or so out of it. A properly maintained one run under normal conditions with no history of problems should make it that far.
