Question about Heating & Cooling

1 Answer

I have a discontinued (around 1991) remote heating unit model ERGW 0012-1A/ P68191-6F. I need to replace the combustion chamber (heat transfer chamber). It is identified as #1 and #2 in the heating system parts picture page. I am hoping there will be some old parts somewhere. I will use an HVAC contractor to buy it but I am trying to find the part if I can. John Wisda (805) 525-9707 Ventura, Ca

That is an Amana and if it is under warranty you have to get an authorized repairman. if it is not then the cost of the part after shipping and labor will be about the same as a new unit. if your going to pay a contractor to do it any way and most new units have a vey good warranty for their gas furnace.

My furnace works on ac and blows on ac but on heat it does not blow but i hear a humming sound coming from the furnace

Most furnace operating on Oil or gas will heat the combustion chamber before starting fan to prevent cold air draft at start-up, can last a minute or two. Eiter the main flame does not come on or the chamber thermostat have fail. Try to modify fan option on room thermostat from auto to on. Cold air coming out: burner problem or no more oil or gas, warm air: burning chamber thermostat problem, leave room thermostat fan option to on until repair.

My statis code reads #33 which limit flame or roll out switch is open i dont know where to locate a roll out switch . i just never work on this heating unit

The flame rollout switch should be located in combustion chamber directly above the burners.Most of them have a red reset button in the center. Check to see if it will stay in when you push in on it. If not then replace it. Hope this helps you.Thank you.

Hi, not knowing what kind of unit you have, I can say this...., if it is the combustion motor at the indoor unit if this is what you have, on a call for heat the 1st thing that comes on in the sequence of operation is the inducer/combustion motor. It should have a poly type hose or tube coming off of it and going over to what is called a pressure switch. It has a single set of N/open set of contacts that have to close before anything else will take place. This is where you need to start. You can take a piece of jumper wire and jump across this switch, and if it is stuck open it will fire up, IF this is the problem. If it fires up, remove the jumper wire and check the hose for kinks, holes, ect. Pull the hose off of the motor end and blow in and out on it to see if you can free up this switch. If not, and it did fire up when you jumped it out, replace it. It is a safety, so do not leave it jumped out to run. Get a switch at a appliance parts house. If this is not your case, send me the name , model & serial number of the unit, and we can go from there.

Just had some work done on a Goodman GMPN060 and was told the heat exchange had a crack in it. Checked and the part itself is under warranty excluding labor. Just wondered how big a job it is and if...

you correct these heat exchangers are either warrantied for 15-20 years on the units... but the labor usually is not.... been appliance/heating /and air conditioning business owner for approx. 10 years now and in the business a little over 18 years .. the heat exchanger labor usually runs around 600.00- 800.00 when we do these jobs under warranty... it requires diassembly of practically the entire unit in order to do it correctly... and that usually requires unistalling the unit and re-installing in order to get the job done.,,, if the unit is over 12-15 years old we usually recommend replacement ,but does not have to be the finally result... as far as changing it out i won't say it cant be done by a home owner it is alot of screws and like i said requires diassembly of the burner chamber ,combustion motor ,flue piing,gas valve,any safety switches and wiring in the way...the heat exchanger is located on the burner side of the furnace in behind all this is the burner tubes and a plate that has to be removed to gain access to the heat exchanger. it not all that difficult just time consuming... as far as a diagram or step by step instructions i am not aware of any available.. they do have instructions in the new heat exchanger that gives a brief description of what required and a picture or two on it... 5k seems a little expensive too... i am in the dallas /ft.worth metroplex and we charge on the average 3500.00 to install new furnace unless there is special circumstances or going to be a real chore requiring several guys... hope this helps good luck ....

I have engineer who wants to install this direct vent heater about 14" above the exhaust of the heating unit , my concern is the water heater would bring in products of combustion from the heating...

You should be concerned since there may be a possible transfer of condensations or c/o. If the vents are off set by 3 feet one way or the other and 14" above, there should be no problems as long as it is not an in a closed area.

I have a Payne, Gas heat/Electric cooling unit, model# PY1PJB____, and apparently I need to replace the combustion blower wheel. When I turned it on 1st time this season, it made a very loud noise, and...

Hi, you will need to replace the inducer/combustion motor as one assembly. If you know any contractors that have a c-20 or c-38 license, you could get it at any wholesales a/c & heating parts house. If not, you will need to buy one on the Internet, just enter the name, model, serial number of this unit, and you can order one. Or, take the assembly out and go to a appliance parts house, they may have it in stock. Very easy to replace.With the wheel broken that way, I am sure you have bearing problems that caused this problem, so I would get the complete assembly. You will be better off in the long run.

roll out occurs if there is not enough combustion air at the burners or there is a blockage of the vent pipe. check both for problem. a blocked heat exchanger can also cause a roll out.

I have a tempstar combine air conditioner and furnace. the furnace will run fine then the manual limit switch trips. i can reset the limit switch and it will operate a couple of cycles then trip again, any...

If the unit is around 6 years old then it could be the combustion air motor. If the unit is older then you need to inspect the heat exchanger for signs of cracks. Take the top off the unit to inspect. Check to see if the metal around the reset is hot and if it is then the switch is doing it's job. If the heat chamber is cracked then turn the gas off, because your home will have CO. This can kill you.

Heat does not work when thermostat calls for heat...

This is a safty limit switch. Find two wires that are going to the inducer or combustion blower that terminates to a small disk about the size of a penny. In the middle of those two wires should be a small button. Push firmly down thus reseting the switch. This should do it. It could also be the pressure switch but I have never heard it called that before. If the first doesn't fix the issue. Remove the small tube that runs from the inducer to a black or silver disk, blow out and draw in air until you hear clicking noises. Sometimes they can become stuck. If that doesn't work, remove the other end of the tube from the pressure switch and blow through it. Sometimes debris can clog the entrance to the pressure switch as well. Hopefully this will solve your problem. You can have a bad limit or a bad pressure switch. In this case you will probably have to call someone out.

A model number may help. Also, are you refering to the inducer fan?

If so, jump out the pressure switch. If it runs, start looking for a blockage in the combustion chamber, blockage in the line to the pressure switch, a bad inducer fan (not getting enough pressure to close switch) or a bad pressure switch.
