Omega Trane Furnace Draft Inducer Blower 115 Volt Variable Speed Fasco # A190 - Answered Questions & Fixed issues

You could have a shorted gas valve.

Well if you held the pilot knob down for 1 to 2 minutes before you turned it to on and it went out your thermocoupler is no good and needs replaced

No pilot feed or it is dirty and or cob webs may be disrupting flow. Clean every thing and relight.

Now getting enough oxygen. To much fuel but it can not breathe try adjusting pilot nozzle.

Are your air filters relatively new? Is a bird nesting in your units combustion air exhaust pipe? Does your draft inducer motor run before and after the gas has ignited? Check and confirm these 3 things first. Good Luck!

This is not a "tool" question, you should have posted to Air Conditioners. eBay doesn't list any right now, last one went for $50. Is it the control board or the fan or both that you need to replace? Might be able to find the control board separate if you have that number.Best bet if you have the time, is eBay, Craigslist or a local heat and air repair guy who might have an old one he can sell you.If you are lucky:Ten-year internal functional parts limited warranty is effective on units installed after October 1, 2001 and manufactured January 1, 2000 or after. Earlier installations have two-year parts warrantyhttp://www.customengineering.info/products/esxv90.html

Must be AC - I've never heard of a 115v DC supply.

Could be correct, or you may have something in your fan that either fell into or crawled into your fan through the exahust duct.Since you have a service contract, have they actually been out to look at it or did they tell you that on the phone. It might be worth removing the fan and clear any forign matter. The problem is the labor to do that would be the same as to replace it. What does your service contract cover??

It sounds like the fan limiter switch is going bad. This switch waits until the air temp is high enough for heating the house before allowing the fan/blower to come on. There is another switch that shuts off the blower when the air drops to a certain temp, or it may be the same switch that does both jobs. Hope this helps.

dodgy relay possibly

The fan runs continously because your condensor is not kicking on and removing the heat. The thermostat needs to come under the set temp. to kick off the fan. If your compressor doesn't run and the fan on the outside unit does run, your compressor has an issue. If nothing runs outside, then your transformer on the inside unit(air handler) has an issue. This could also be a control relay on the condenser or the air handler.

When a furnace is replaced with a newer style unit like yours with an inducer motor, they sometimes use the old vent pipe. These old style vent pipes are transite (light weight cement), the moisture created from your furnace exhaust is caught on the cool transite surface and runs back down into the blower blades or wheel bringing a white mineral deposit with it which causes your problem. The vent should nave been replaced with the heater using a metal vent material. You will need to replace your inducer motor assembly and vent pipe to prevent a recurrence.

THIS IS A COMMON PROBLEM WITH THE DOOR SWITCHES, MY FIRST ANSWER WOULD BE REPLACE THE SWITCH SECOND WOULD BE OPEN THE DOOR AND PUSH THE BUTTON IN AND SEE IF THE FURNACE WILL WORK. THIS SWITCH IS JUST A DOOR SAFTEY IF THIS WORKS. I HAVE TAPED A PIECE ON THE INSIDE OF THE DOOR WHERE THE SWITCH WILL HIT THE DOOR ABOUT A 1/4 INCH THICK AND SEE IF THIS WILL GET YOU RUNNING UNTILL YOU CAN GET A SWITCH

When you shorted it you may have caused internal damage to the compressor or blown the capacitor

pressure port is plugged pull hose off draft motor and clean port with a paper clip

sounds like your drain is stop up in wich is filling your air swich up with water the causes a miss fire the indoor motor will run untill you turn it off when this happens

high limit is open try tapping on it gently

Your second stage heat check the dip switches on the board and the wires to the proper two stage heat t-stat.

How about the Heating/cooling thermostat. Sounds like you better check it. If you need further help, I’m available over the phone at https://www.6ya.com/expert/craig_3fa289bf857b1a3c
