Along with the exchanger you will need header gaskets, manifold gaskets, Pressure switch and tube, igniter or pilot and maybe a temp sensor. I count on all of these when I do an exchanger, total cost about $300.00 Now your over a grand. Labor about two to three hundred, if nothing goes wrong, and hopefully it all get's done right. Now your up over half of a new one and 90 days on parts. I know I make money at this but I make money at rebuilding heaters also. I usually try to get people to go towards the new heater.
Then take a course in pool and spa chemistry. 99.9% of the time this is the cause of a bad exchanger and that is what hurts the other components at the same time.

Master temp 400 2 yr old bad heat exchanger??

i dont blame you for your frustration!! i have hadseveral customers who had great water chemistry and had the heat exchanger fail. if you have a salt water pool, you should have been advised to purchase a heater with a cupro nickel heat exchanger instead of just a copper one. otherwise since ur chemistry was spot on, then you unfortunatly purchased a bad unit

How to replace swimming pool heater core

I assume you are referring to the heat exchanger. Usually when these fail the heater is replaced. Reason being that this is the biggest money part of the unit. The part alone will run pretty deep into the price of a new heater.
Then you still have the old burner tray, old gas valve, old thermostat and old internal ignition device. Each of these components run several hundred dollars apiece. It doesn't make sense to throw good money after bad.
If this exchager was leaking from a salt water pool (common these days) it would be advisable to replace the heater with a Sta-Rite MaxiTherm with the cupro-nickle exchanger. This part is coiled which allows for better water flow and less corrosion than a standard copper exchanger.
To replace the exchanger is not all that tricky if you are handy with a screwdriver, wrenches and plumbing. If you have any doubts get a pro over. Remember you are literally playing with fire.

Water flows out the condensation tube even when the heater is not runiing causing the pool to leak down. The heater is 4 years old. Thank you.

It sounds like there is a leak in your system. The condensation tube is to drain off the water because one of the byproduct of combustion is water and it condenses on the heat exchanger. Since it is only 4 years old it might be under warrantee for this issue. The problem might be simple but could be very expensive if the heat exchanger has a leak.

Water is dripping down inside the heater on the left side,pool co. says I need to buy a new heater. Any thoughts?

The heat exchanger is the problem and it is expensive to fix. If the leak has gone on long enough to damage other parts or the heater is getting older than 8-10 years then it is likely better to replace it.

If the unit is newer and in decent shape then fixing it is an option but total for parts and labor is nearly half the cost of a new unit so consider carefully if the repair is really worth it.

LLD125 pool heater leaking water from inside

My heat exchanger was cracked. I found an old welder who knew how to weld the cracks for $100 vs $900 for a new exchanger,. Also ordered replacement seals for the 2 chambers. I used high temp automotive engine sealant as an additional sealant precaution. Also inspected tubes and cleaned corrosion. Works fine last 3 years. Takes some mechanical skills.

You need to buy the whole unit as these are pressed in place together. If you have a leak it is most likly due to chemical damage and goes further. So at the least you will need an exchanger. I will usually try to get people to go with a new heater if it is more than a couple of years old due to cost and hidden damage that can only come out after you install a new exchanger. Sorry for the bad news.

You can try to get a welding shop to tack it back in place (I do not remember who to credit for that but it was not my suggestion) and see if it stops.

The exchanger is expensive as a DIY part...about $350...but if that is all that is wrong it is a lot cheaper than $700+ for a whole new unit.

Jandy Lite 2 LG250N- Heat Exchanger cracked over winter

Yes I just had the same problem, the guy that I bought the house from told me to drain the pump and the filter,etc. But failed to mention there is three brass plugs on the side of the unit, so the heat exchanger cracked, but i took it to a general welding shop and they welded the crack up so that saved me a bunch of money That is all you have to do
