I have an old MOC-80-1 furnace in my mobile home. Seems to

Good afternoon, I have an old MOC-80-1 furnace in my mobile home. Seems to be working well. Co2 detector in the vicinity, but not in the closet with the furnace. Combustion chamber is shot so I will need to break it down to replace and clean it while I am in there. Should I just buy a new furnace?JA: Did you check the furnace's filters?Customer: There are no filters. It is an permanent indoor filterJA: Do you plan on doing the work yourself?Customer: No Co2 issues I was thinking about it.

I installed a I c p furnace 3years ago in my

I installed a I c p furnace 3years ago in my trailer,converted it to a down flow and put an a coil under it with a transition boot to my existing ductwork and it has ran great up until December,2015. I had a trouble code of "ignition proving failure" 6 short flashes and 1long meaning it tried 3 times to answer the call for heat then locked out. Tried the component self test cycle,checked current value of flame sensor,was low so for $8 I changed,checked gas input pressure,even called gas supplier and the tech checked pressure at the meter while I had the furnace,the 100,000 b t u demand hot water running and 5 burners on our new stove no pressure drop at all at meter! January 15,2016 I was home and heard two loud bangs then furnace dropped out went to see trouble code it was " limit circuit fault" 4 short flashes which meant the flame rollout sensor saw a backdraft of heat off the burner! Had a company come in and it dropped out on a 6 flash code while he was working on it,checked the high limit disk and it was open,caught it before it cooled and reset itself so he changed it on January 20,2016. It ran good for 4-5 days then same 6-flash code again and a lockout. I have tons of return air grilles on the closet door,behind the fridge,and thru the floor in the closet too! The furnace closet door used to slam shut if you held it open 6" but now with all the return air available it does not. Any suggestions or thoughts on this would be greatly appreciated! Some guys I talked to say the insulation may have come loose around hi limit disk and obstructs air flow to it makes sense? I really need to be able to trust a 3 year old furnace oh by the way not a single issue with the air conditioning part of the system no coil freezing great temps off the air registers will take my 43 year old trailer down 10 degrees in less than an hour! I don't know how to troubleshoot the secondary heat exchanger to see if it's clogged its plastic not stainless I have vacuumed the primary tubes with a 1" soft bristle tube brush wasn't that bad! I've covered igniter resistance cold(51.2 ohms) flame sensor hi limit disk even shop vac the vent pipes no nests or spiders

I have a rhp115 sn#04030251 it has been heating my pool

I have a rhp115 sn#04030251 it has been heating my pool wonderfully for the last 11 years but it started leaking out of the bottom of the unit yesterday. I looked down thru the top and couldn't see anything really but it was flowing out of the bottom of heater at a somewhat noticeable flow. it was late I was tired so I didn't dig any deeper into it. Is there a common parts that fails or starts leaking after these heaters become a certain age I can replace without a lot of grief.

We have an Alpine Gas-fired hot water boiler (model#

We have an Alpine Gas-fired hot water boiler (model# *****), installed in 2009. On attempting to do the annual inspection, the technician found a stripped screw on the heat exchanger and refused to do any inspection pending replacement of the heat exchanger. Is the heat exchanger needing to be replaced? The unit continues to work without fail over the past 4 months. The heating and plumbing company is hedging on the price of the replacement with a rough labor cost of $2000 plus the heat exchanger.As this company installed the unit, it was best thought to use them. But if this is a straight forward repair, the home warranty company has their local contractor who is willing to do the replacement at a lesser cost.Can we risk running with the unit until it breaks?
