Question about Teledyne Laars HEAT EXCHANGER ASSEMBLY, DP-350 - 10403602
I have in floor heating in lower level and forced air upstairs. I have to light the pilot light a few times a day. I've taken out what I think would be similar to a thermocouple and emery clothed it down. I cant remember for sure but I think I have had to do that before and it worked. Could it be that that part now needs to be replaced. Also yesterday it was going out more regularly so when I lit it the last time I left the cover off thinking I would need to light it again but it hasn't gone out since. 12 hours so far. Any help would be appreciated.

SOURCE: Pilot light wont stay lit
If this is a new item then you will need to let the gas run alittle bit longer. If this is a used item then it sounds like you are going to need to replace the flame sensor. You may have to even do it on the new item. But usually for the first start you willl need to hold the pilot down for about 1 minute to really let things heat up in there then when you release all will work

It sounds like a thermocouple has gone bad. this is a very common problem with gas powered things ie; water heaters, furnaces, hot tubs. The telltale sign is when you release the pilot light button it won't stay lit. This is a safety feature and is relatively inexpensive and easy to repair.
