Heater - Seems to have no electric power

letmetellu · Jan 9, 2007, 08:02 PM

If you have checked the power plug that your furnace is plugged into and you have power there then is is something in the furnace itself. There is a door switch that has to be pushed in before you will get any power. So to check this turn the thermostat fan switch to on and then push in the door switch with your finger, if the fan runs it is possible that you are not getting the door on right and it is not compressing the switch. Check these things and then let me know what happened.

Check for a fuse on the control board, usually one of the automotive style blade ones. Even if you have power to the furnace, not much is going to happen without the 24 volt control power.

In checking the heating unit, I see that my Honeywell Enviracare has no power light lit and the heating unit seems to be in the same state -- no power. The outlet for the units is working. Flipped the fuse switches at my box off and on. Flipped the gas switch off and on.

What would be the situation here?

Thanks very much.

Thanks for the replies

I keep looking for the furnace switch on the unit itself, but can't find one for some reason. The woman and the hvac place said it could be the door also. There is a wall switch w/the power cords to the unit that I flipped off and on, but nothing other than the one plug has a light that goes on.

I did press on the door (which I have never taken off and it doesn't really look removable) just in case it wasn't tight somewhere, but nothing happened.

Does it make sense that both the Honeywell filter unit and the heating furnace both are not powering on? The air conditioner does go on (it's a thru-the-wall unit that I thought was somehow connected to the furnace system for output, but I think I now realize they are prob quite separate and I'm just hearing the compressor start. Didn't wait for any vent noise or anything, just quick turned it off.

Thanks.

The lighted plug shows the outlet is hot. You or a technician are going to have to go inside. Have you tried sliding the door up? There may be filters in there that need changed or cleaned regularly. Usually there is a switch that cuts the power off when you open the door. Then look for the fuse.

The Honeywell unit could power off or at least be controlled by the 24 volt transformer.

I am not familiar with that unit, and am only answering from my general knowledge of heaters.

The plub is hot? I thought that was just an 'on' inidicator light?

The serviceman was just here -- it's my thermostat. He said a new unit is $500, and it only has a 30-day warranty. Lexpro I think the name is. Anyone familiar with their quality?

So, I told him I need to research thermostats a bit because I don't want to get the same one -- $500 every few years. He charged me $60 and another $99 for not buying a unit from them (goes towards purchasing another one of their thermostats). Essentially charging me for a unit I didn't buy.

Is this a customary practice if I choose not to replace my parts?

Should I not have mentioned I was going to look around?

I have ordered a new thermostat -- 2-stage heat/2-stage cool. I think my a/c might be 1-stage cool though.

Is the 2-stage cool OK with the new therm? Meaning, up to -- either 1- or 2-stage cool systems?

Are these easy to re-hook up? I am computer literate and have tinkered w/hardware (installing new drives, memory, etc.) The tech said if I do anything with the wires I could ruin the heating system.

By hot, I meant the outlet had power. The indicating plugs like that can be nice.

My furnace and A/C are both 2 stage, but have their own logic allowing me to use a simple, 4 wire thermostat. You would need an installation manual for yours to figure it out if you could.

It is hard to do more than burn up the control thermostat if you miswire a thermostat. Even if the fuse doesn't save it, you can buy one for $10-$20.

With the thermostat controlling multiple stages, you have more wires to worry about. To white to the W and yellow to the why, you need more wires for what you have of W1, W2, Y1, and Y2. You will have to open up the furnace and see what terminals you have and what color of wires are on them. Then try to put the same wires on the same terminals of the thermostat. Note, connect the red wire to all of are, RC, and RH. Post back with any questions once you have the thermostat instructions.

Hi LabMan,

I have the thermostat from Totaline and have read the instruc for putting the receiver on the wall. What I find that is different:

My current LuxPro has a RH and RC jumped -- the new one has neither.
A red wire goes to RC -- there is no RC on the new one.
I currently have batteries in the thermostat -- the new one has none.
The old therm was a 1-stage cool -- the new one is capable of 2 stages.

G-Y1-W1-W2-RH-B-O-RC Old config (red going to RC, RC/RH jumped)

C-G-Y1-W1-R-Y2-W2 New config

Old therm directions say the RC-RH are jumped when there is only one compressor.

There are also dip switches in there for the remote, but no real explanation other than they all need to be set to the sum (house#) for the ones set to ON. ? How do I know which ones to set on 1,2,4,8,16,32,EH,HP,O/B.

Thanks for your help!

All I'm going to say is...... 500 dollars for a Luxpro.............. I'd show him the door so fast he wouldn't feel it hit his back side until tomarrow.
I'm afraid to ask how much that company charged you for a Goodman furnace.
