Mike the plumber :

Hello I'm Mike. I'll be glad to help you with this issue.

Mike the plumber :

Sounds like the thermocoupling has gone bad and needs to be replaced. Not sure what you mean by going into vacation mode though. Most heaters have to manually be placed on vacation mode.

ouch.. there is a steeing on the thermostat that allows you to set it in vacation mode. i lowers the temperature while you are away. Yes this one for some reason is going into that mode itself. when i try to set the temp/reset it the pilot lights. then goes off. It will do that a couple of times then the vacation mode light comes on then I can't do anything to set temp.

Mike the plumber :

The only other thing that can be causing the heater to got out is a lack of combustible oxygen. meaning the fresh air inlet is clogged and will have to be cleaned

Does your heaters control have 6 or so lights? And a whiteish cover?

Ok, Im sorry for the delay, got a nasty headache after dinner. What you have is the intellivent control. Here is the sequence of operation on the heater from service manual. What i need to know is how far the heater gets into the sequence

 

1>Field wiring correct?

2>Call for heat

3>is pressure switch proven within 5 seconds

4>Blower on

5>Is blower switch proven closed within 5 seconds

6>signal to ignitor

7>Ignitor warm up time

8>is flame sensed gurring trial (do the burners ignite?)

9>is flame sense maintained? (burners stay on)

 

Now I can tell you this, the flame sensors are very finiky on these models and chances are you will need to open the inner door and clean the flame rod with some steel wool or open mesh sand paper.

 

On this control Vacation mode siomple means the temp is approx 70 deg or lower.
