hi, First thing is double ckeck and make sure ur t-sat is set for cool and fan swith is set for auto. Have u done any mowing or used a weed eater recently, if so, check very carefully the small diameter wire that looks like t-stat wire its usually brown, for any cuts on it. If u find any. shut off p...

Flame being smaller can be caused by a blockage in burner tube , gas valve, gas line, low gas pressure, gas valve going bad, ect. What do you mean by wont heat up house, do you mean it wont reach temp srtting on t-stat, wont ignite, low or no airflow from vents, some vents have airflow, can u be mor...

ck roof jack for seperation, flame should be blue. does pilot stay lite after u light it, w/o out going out. If so, when blower kicks on does the flame move alot. its possible u may have a spider web in the pilot tube/ burner or even in the spud behing the gas valve. Let me know what the flame does ...

part # 621486. I recommend u purchase it from this site. I'm curious as to why u think u need one. If infact you know for sure that u need one, and found the reason ( short the secondary system, i. e. t-stat wires, ect.) and fixed the problem, I suggest you put a 3 amp " auto" ATC fuse inl...

Can u post more info on your unit, I'm coming up with an a/c using that model number. Its possible that the database I am currentley using is wrong. Is this a pilot lite , hsi, extra. Are u sure the model u gave is for the furnace and not the a/c part. Like I said I could be off track here. U might ...

Based on your post it could be a number of things including a problem with a heating element, a bad sequencer or one going bad, an open limit to a element, ect. First thing is check all circuit breakers. Before we go any farther, this furnace involves HIGH VOLTAGE 220V. This is extremely dangerous. ...

Hi,

This something that should be addressed by a technician. Some3thing is definitely shorting out.
The breaker tripping is a safety net. Dont keep flipping the breaker on. This unit should not be operated till its fixed. U have a baby, do u both a favor and get it fixed right.

Vacuuming it out and changing the filter is a good start. Don't take this wrong, but how long was it prior to this change did u last change filter, if it was quite awhile, or its been awhile since a tune up was done, the blower wheel could be dirty. usually when a unit goes off on limit, its because...

hi, there u say u have 24v at W board terminal, but zero at C. i believe Robert wants u to place 1 meter probe on the W terminal on the board and the other meter probe on the C board terminal and ck for 24v. i am curious as to where u put meter probes an got 24v at w terminal and 0 at C terminal. ma...

As a suggestion, u might have better luck using a couple of large cresent wrenches or better pipe wrenches

I'm not completely familiar with this unit, however,u said it ignites for a few seconds, do u mean the ignitor just glows or do u have flame? If u have flame, it sounds like the flame sensor is not detecting the flame. If this is the case u can use a piece of LIGHT sand paper or a green kitchen scra...

the most likely cause based on your description is a faulty fan switch
the can be ordered from this site at a reasonably cost.
remember to turn power to the unit off, before disconnecting/reconnecting the fan switch.
go to the parts section of this site

Its possible the high limit switch is bad. The fan switch could be faulty. Does this unit have an a/c box, if so is the t-stat 2 wire or 5. Its been awhile since i worked on one. One of the moderators. a gentleman by the name of Robert, is an expert here, u might be better off waiting for his reply,...

If you wired it up correctly, which appears to be the case, Its possible that u got a bad motor, however, its more likely u have a bad capacitor. Is the cap buldging or in anyway disformed? Check and make sure the capacitor wires are still connected securely, I have ran into a situation where anothe...

U either have a weak/loose breaker or something is drawing to much current. How much experience do u have with a DVM meter? If u dont have alot of experience, its best to call a pro. U can start by shutting off the power to the outside unit and checking to see if every electrical connection is tight...
