SOURCE: Goodman Furnace/AC unit not working

3 amp is standard.the fuse is blowing to protect the transformer.It is telling you that there is a short in the low voltage wiring.Goodman also had an issue with the coil shorting on the contactor.To prevent damage.....i'd call a pro.It should be a fairly simple repair.

You need to type GOODMAN GAS APPLIANCES into you browser to find you local servicecenter. I must tell you that Goodman only sells to authorized service companies in my experience. So you become EgKraft Company.

1 FLASH
Furnace fails to operate.
• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.
• Failure to establish flame.
Cause may be no gas to
burners, front cover
pressure switch stuck open,
bad igniter or igniter
alignment, improper orifices,
or coated/oxidized or
improperly connected flame
sensor.
• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy
burner flames (improper gas
pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.
• Check front cover
pressure switch
operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
signal. Sand sensor if
coated and/or oxidized.
• Check flue piping for
blockage, proper
length, elbows, and
termination.
• Verify proper induced
draft blower performance.

I have a Dometic DuoTherm ac/furnace unit in an rv. The thermostat got knocked off the wall and now the ac nor the furnace will work. Fan works in manual position only. What could be wrong?


When the thermostat was knocked off it may have damaged the wiring. I would start by checking continuity of all wires from thermostat to unit.

Multiple clicking sounds coming from AC unit before AC unit turns on or before furnace turns on.


the is a 24v wire that feeds from your thermostat to your unit, inside there is a contactor that engages, this makes a click sound as it really is a basic mechanical part the makes metal touch metal to allow current to flow through the system, perfectly normal, your hearing the low voltage engage the highvoltage at the contactor.

THERMOSTAT WILL NOT COME ON.


You may have missed the fuse. It will/should be part of the control board and has a 3 or 5 on it. You can jump R to G at the tstat by touching them two together. If you don't feel comfortable doing this then don't do it. G will bring on the fan only. And if it starts then you probably have a bad tstat. If not, then you have a short that damaged your 24volt transformer, or lost power to the whole unit. Check your breakers!

Thermostat will not come on, therefore unit will not come on


Your thermostat is probably wired directly into the furnace to supply the 24V to power the stat. You have to make sure you're getting 120V into the primary side of the transformer, and 24V out of the secondary side. If you've got voltage in and nothing out replace the transformer with one of the same voltage, and same or higher VA rating. If you don't have 120V in then start checking backwards starting with power in/out of the door switch, then back to the unit disconnect switch, and back to the breaker if necessary. If you've got 24V out of the secondary go check to see you've got 24V at the thermostat between the R and C terminals, if you do the thermostat is bad. As with any electrical wiring make sure you've got good connections on all wiring terminations. Good luck, if you need an explanation of how to check the power in and out of the transformer let me know!

My rv furnace want start up i changed ac units new don't have the relay box build in it how do i rewire the furnace ?


Shooting from the hip here, but look at both the new and old wiring diagrams. Chances are that the new unit has terminal leads that would connect to the old units' relay/control box and you simply need to install the old box on the new A/C by connecting to the correct terminals. beyond that, you can build your own relay setup if you understand wiring diagrams. If you don't know wiring, I'd recomend taking to an RV shop, as you can damage either the A/C or the furnace or both if wired incorrectly... Hope this helped!

Hi Proper way on wiring furnace.


I can give you a start, For heat only, R terminal on furnace to Red wire to R or RH terminal on thermostat. W terminal to White wire to W terminal on thermostat. G terminal to Green wire to G terminal on thermostat. This will get you heat but not air conditioning.

Having a problem with my AC/Furnace. AC was working fine and was turned on for about 3 weeks. Thursday night it cooled off and we opened up until Saturday morning. On Saturday morning the AC would not turn...


I think your problem is poor usage of the device,i.e. overloading the system. try running better cables to your furnace and ac. The reason i am lead to believe that is. If you already hired a pro to come and fix it for you,and he/she could'nt then what else could it be? in my experience ac units use electricity like microwave ovens.and power tools

I need help selecting the best Amana 5 ton furnace/ac.


I believe you are asking which furnace to go with?

Just some clarification first.

The "condensor" is the outdoor unit.
A "Compressor" is the device inside the outdoor unit that pumps and "compresses" the refridgerant.

An evaporator is the indoor coil, it has refridgerant running through it.

The furnace is completely seperat from the condensor and evaporator.

I "THINK" you are saying that you are looking to buy an AMANA system with a 5 ton 14 to 16 SEER condensor, and a furnace, but you need suggestions on the furnace.

typically when you purchace a condensor, the evaporator coil is simply matched by the manufacturer to the specific condensor you purchace, there is no choosing to deal with. All condensors ofcourse come with a compressor already installed.

If my assumption about your request is correct, maybe this will help.

Amana's 90+ furnaces are great units. I would recomend them to anyone. The 80+ uses a somewhat inferior heat exchanger, and is ofcourse less efficient.
Anything higher than a 90+ can take quite a while to recoup the costs of the enitial purchace through your efficiency savings.

If it were my home, I would go with the 90+ furnace, and the 16 SEER Condensor/evaporator system. But ultimatly, its up to you, your efficiency standards and your wallets potential.

If you live in a northern state where AC is little needed, I'd go with the 14 SEER AC.
Again, an initial cost verses long term savings issue.
