How to fix your furnace and save the $200 service charge
Updated on February 8, 2008 carson08 moreContact Author This is barely the beginning…
Hi everyone, this is my first hub and if you do not like it let me know and i will tell you why i don’t care. 🙂
I work in the HVAC Service Industry. Strictly commercial, but i do know all about residential as well. There are particular things you should not pay for, because some of the basics are just so basic knowing absolutely NOTHING about your furnace or air conditioner you possibly can still fix it and save yourself the staggering price of somewhere between $99 to $159 an HOUR for hvac service.
So let’s get started with the FURNACE.
Listed here are some basic tools you may need almost definitely.

-1/4” hex nut driver
If you don’t have those tools don’t fret about it, you might need them and you may not. So here is the 5 most basic items to check your furnace for BEFORE calling your tech and dishing out the dough.
THE FURNACE SWITCH
i am unable to REMEMBER How many COUNTLESS TIMES THE SWITCH THAT TURNS ON The ability TO THE FURNACE HAS BEEN TURNED OFF BECAUSE SOMEONE THOUGHT IT WAS A LIGHT SWITCH.
Best method to check if its on is look on the switch. In case you have an all electronic thermostat and its blank, good chance your switch is off.
2. THE BREAKER
PRACTICALLY The identical As the ON/OFF SWITCH, SOMETIMES THE BREAKER JUST GETS TURNED OFF BY MISTAKE. TURN IT BACK ON AND LET IT RUN FOR A few minutes. IF IT TRIPS AGAIN You will have A nasty MOTOR OR A WIRE TOUCHING GROUND, IF You recognize ELECTRICAL PROCEED WITH CAUTION, IF You don’t, Now could be THE TIME YOU JUSTIFY CALLING A TECH.
3. LOOK WITHIN
ON ALL NEWER FURNACES THE OUTER DOOR HAS A SMALL HOLE SOMEWHERE WHERE You may LOOK THROUGH THAT HOLE AND SEE A BLINKING LIGHT. SOMETIMES You must TAKE OFF ONE DOOR TO SEE IT. THAT BLINKING LIGHT IS A CODE.
LETS SAY IT BLINKS 2 LONG BLINKS, 3 SHORT ONES, Meaning 23.
LETS SAY IT BLINKS 8 SHORT ONES, Meaning 8.
AFTER You determine THE CODE ITS Giving you, AND CHECK IT 3 TIMES To ensure You have got The precise ONE, KILL POWER, REMOVE THE DOOR YOU WERE Looking at, AND CHECK ON The opposite SIDE FOR THE WIRING DIAGRAM GLUED TO THE DOOR. SOMEWHERE ON THAT Must be A CODE REFERENCE, MATCH UP THE CODE, AND SEE IF ITS SOMETHING You may FIX.
IF IT SAYS SHORTED FUSE, CHECK STEP 4. IF IT SAYS GOING OUT ON HL (HIGH LIMIT) CALL A TECH. BASIC FIXES You can do, BUT REMEMBER ANY TAMPERING With your FURNACE CAN VOID YOUR WARRANTY, SO Do not DIVE DEEPER THAN You may SWIM.
4. The 3 AMP FUSE ON THE BOARD
Here is where it starts to get tricky. This one requires a couple of steps.
Turn the ability to the furnace off. Either flip the switch or kill the breaker so you do not get shocked.
Take the furnace door off. Depending on the brand there can be between 1 to three doors, take them off so you are looking on the electrical section of the furnace, typically wifi programmable light switch timer in front of the blower door near the bottom of the furnace.
Search for a small fuse. It looks like this TT ignore the lines sticking outsideways on the 2 t’s and that is what it is, basically a fork that is purple or orange that plugs into the board. It would read 3 or 5 on it.
Pull out that fuse if it has one, sometimes its got a reset, sometimes it has nothing, but if it does, pull out that fuse and check it.
If the small wire connecting the 2 sides has popped, go to a hardware store and buy a small box of 3 or 5 amp fuses, replace one and see what happens, if it pops again, you have got short somewhere, if you cannot see wire rubbing anywhere, call the tech, you may have a low voltage problem.
5. Last One-Air Flow
Say its summertime and your not getting very much cold air blowing out, you go outside to see if your ac is working and see an enormous amount of ice on the larger copper line going all the best way inside your home, go inside and lo and behold its going inside your furnace as well.
Or say its wintertime and your not feeling any air popping out of the vents but you are feeling lots of heat and whenever you go downstairs you see its all working best you may tell.
CHECK YOUR FILTER
EVERY SINGLE SYSTEM HAS AN AIR FILTER DESIGNED TO TRAP DIRT AND DEBRIS FROM GOING INTO YOUR BLOWER MOTOR AND CAUSING DAMAGE. IF THIS FILTER Isn’t REPLACED EVERY 1 To three MONTHS, THE FILTER GETS TOO Packed with DIRT AND THE AIR CANNOT EASILY TRAVEL THROUGH IT. WITHOUT ENOUGH AIR GOING OVER THE COIL IN WINTER OR SUMMER, YOU CAUSE MASSIVE PROBLEMS. NEVER LET A FILTER GET EXTREMELY DIRTY!

Thanks for all the info! Question for you my furnace is squealing horribly when the heat is running. Its an Amana air command. Can i just turn it off and open the bottom door and oil it or is it going to be a production I don’t wish to mess with it if it is going to just make it worse!

Alright I had the same thing. 3 amp fuse keeps blowing. I don`t have an ac hooked to this like rather a lot of those posts everywhere, only a furnace and a thermostat for heat. I`ve been working on this for two days and that i can say in any case this I found that I had an intermittent problem but didn`t comprehend it. I`d check something and then 20 mins later I`d check it and it was different. Be sure belongings you already checked are the identical 20 mins later. Overall, i discovered thermostat wire wore thru were it enters the furnace and shorting to ground. i changed the board and thermostat, but because it turns out it was the short and no need for that stuff. One of the best method to fig this out is, disconect the thermostat at the board see if fuse blows, if that’s the case short inside furnace. If not, short out thermostat at board and while leaving thermostat wire DISCONNECTED. If blown then maybe board, or short, keep looking. If it does not short its the thermostat wire somewhere on its approach to thermostat.

i had an idea on how i could get the cold air in my basement to the loft where it is extreamly hot regardless of how low i set the ac temp. After i began doing research i discovered a site called powerzoning.com. if you could possibly, check out the site and let me know for those who think it makes any sense and in the event you think it would be worth looking into further
