1st, take a picture of where each wire goes to. Look in the owners manual for an exploded view of how it goes together. The heat exchanger most likely comes out from the front of the furnace. You will have to remove and reinstall every componant inside the furnace to get it out. Suggestion, replace the whole furnace. It will be cheaper.

Hello, Usually it has to do with the quality of the install and the brand. If it was not installed properly from the beginning then the equipment will fail prematurely. As far as the heat exchanger goes I have replaced many heat exchangers on Goodmans after 3 years being installed, Goodmans are prone to bad heat exchangers.

I have Rinnai R53 tankless water heater which is about 5 year old. recently it has problem to keep water consistant warm. when I take shower , I feel water change from hot to cold antomatically. what is...


You are probably running a low flow shower head and have not had any maint. done on the unit. When the water flow is low and the unit is dirty it can't exchange enough heat to the water and this causes the heat exchanger to gradually increase in temp. The unit then shuts down to allow the heater to cool. This is an automatic reset high limit switch that will turn the burners back on automatically. This problem can be exasperated by 1/2 inch trunk lines. Call a hvac tech in your area to come and clean the unit. He should also be able to increase the draft inducer fan motor speed to allow more cooling of the heat exchanger.

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 ....

Flame rollout on ignition causing rollout switch to fail, prior technician to me feels it is the heat exchanger. I feel that if it was the heat exchanger the rollout would occur after the indoor blower...


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.

Goodman GMNT furnace goes into 'lock-out'.


The brain has to have constant verification of flame. If the burner ground is corroded then you will get the condition you prescribe.

Hi!!! If the flame turns on then off and on then you should change your flame sensor on the gas furnace..YEs flame sensor is shorted..The flame sensor is located by the valve burners it has one wire and is white..Good luck..

Furnace sometimes will not stay lit


Check the heat exchanger for a crack or hole. The room air blower is blowing back into the heat exchanger extinguishing the flame. Have it checked out today. Did you get it checked yet? Now. Have I stressed to you to get it checked out yet or have you been overcome by Carbon Monoxide yet?

I have a Coleman/Evcon Presidential ser# 074878. The plumber says the Heat exchanger is cracked. Is this something I can fix myself or is it less expenxive to buy a new furnace?


The heat exchanger is a bear to change. depending on the age of the unit it might be more practical to replace the unit. However unless you trust this service tech I'd get a second opinion, because it is rare that a heat exchanger will crack, plus by law he or she should have shut the furnace down do to carbonminoxde. Especially rare in Coleman Evcon series units.
