My heater had it's twice yearly service about a month ago and everything checked out. I used the heat for the first time a few days ago and it made a loud noise (like a lawn mower). I called the service company and the technician said that the exhaust fan motor is out and needs replaced.
I find it odd that this wasn't caught during seasonal service visit. Is it possible that the technician didn't put the unit back together properly or something similar that could have caused this? The system is a Trane and less than 8 yrs old.
Hello meglong what type of trane model is it? In the service package that was offered to you was one removing the exhaust fan for cleaning and a minor tune up every year? Because normaly the exhuast fans can be cleaned just by blowing out the fan with some air or even a vaccum cleaner.

If you've had it for about 18 years it may be time for a replacement or, at the very least, a boiler repair. I had mine replaced three months ago and it was 15 years old. I think that it is important to make sure that you replace important things like this about every 15 years just to ensure that everything is working properly and is up to date. How long have you had issues with it? Because if it has worked really well up until recently then all you probably need is just the repair though. Bailey Plumbing and Heating and Air Conditioning
If you had a power surge at your home, and no more power seems to be going to the heater, you must make sure that none of your wires from the load center all the way to the heater are intact and all have been wired correctly and none are lose. If you must be very careful reading manufacturing dates as these dates are actually displayed backwards and the year is actually displayed as the month, you may in fact have an older heater, as sometime when these heaters are purchased by distributors they don't get to sell them until way after or they have had one in storage for a while when they decide to sell them. I have spoken to the guys at the factory and they are very informative, I don't see how they could not help you as I deal with them on a daily and we always try and help there customers, why don't you bring the heater in there service department is great it only takes 5 minutes to fix the heater. If you mail it in its only 24-72 hr turn around.
sounds like perhaps it is time to purchase a newer car and let that one find a new home . our daughter had a problem like this and after much expense was told to unhook every thing electrical she could . ended up being the radio/stereo in the trunk.
Remove and raise upper hose at thermostat end and remove lower rad hose. Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily. Honda rads are cheap.....any restriction....replace rad.
Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose. Flush good.
Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.
Stop leak can plug everything.
Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW! Water pump is optional at this mileage.
Mhenn, It is my guess that the 'electrical burning' smell is from your heating system. Since there is no smoke and the walls are not warm.... then there is no real problem. The smell maybe just dust has collected in the duct work that is burning off the central heating systems electrical heat strips. If you have electrical heat strips then that may be the problem. If you have a central gas heat system, it may be the same type problem. Hope this helps you. Henry
sounds like it maybe the heater again. Have you pulled it out and checked the ohms? it should be at least 10.5 ohms it could be the thermostat or the pressure switch - if either of those are not working it will not heat either.
