    Thank you for your time answering. You've been most helpful and I appreciate the insight.

    power spike removal

    waross - I have considered that there may be an issue with the control board. The fact that it only takes 15 sec for it to trip instead of 30 may mean the R/C ckt values have changed or were never right. It has been doing this since 1996 when my inlaws purchased this dbl wide. Based on its...

    power spike removal

    LionelHutz It isn't a power failure - my TD relay handles that. It isn't a furnace issue - I have serviced it many times. It only happens when there is a weather or maintenance related issue like a blown up xfmr. A brown out won't do it based on my circuit analysis. And the one time it happened...

    power spike removal

    Skogsgurra, thx. This spike isn't killing anything, just causing the ckt to trip out and requiring a finger to reset it. Which is not a big issue if someone is there. But mostly, no one is. Waross, DUH! you can't determine what the problem really is if you are a parts jockey. And most people...

    power spike removal

    @waross Thx,really, why don't they just attach the gen to a bicycle and let the crew pedal? Anyway, if you look at the crt. you see that if the 24v drops that reset may never trip. The sensor drops the voltage across the cap when it sees flame. If the flame quits the voltage rises and trips the...

    power spike removal

    yes, that is exactly what I do. I also pour AF into the sink traps. My brother-in-law neglected to flush the toilets last time. He also bought the AF - I had to tell him auto AF was not so good for septic sys. We also had the refer water valve freeze. A dilemma is that water under pressure has a...

    power spike removal

    I initially considered a UPS, but the went for the TD relay because I thought that the problem was short term drops like 1/4 sec and a UPS would only serve to jump the gap at a very high cost. A power strip would also be cheaper than UPS but I thought at that time it was longer term than a power...

    power spike removal

    When I was there and it tripped it was already running and there were indications of power abnormalities happening, though the power never cut out completely. Generally, the power there is subject to outages a lot more frequently than here at home. If I power the furnace on/off rapidly at the...

    power spike removal

    Not sure if this is the right place for this as it involves a couple things. I have an oil burner on a rural electric supplier. It is a vacation home and the temp is at a minimum when vacant. The issue is the reset keeps tripping - occasionally when someone is there to reset it. Last year we...

    oil burner flame sensor control problem

    Thank you.

    oil burner flame sensor control problem

    thx Bill - I am leaning that way - But since it involves some surgery I would like to understand the mechanism for the failure. The fried TD may have been a coincidence, but a large transient may have caused both failures. I just can't rationalize that. The only way to trip the safety is for the...

    oil burner flame sensor control problem

    I am having a problem with a Honeywell oil furnace flame sensor control. It is, IMHO, a design issue as it has been a problem for years since it was new. Maybe someone can tell me how to solve it. I am a retired EE so I can't just replace it (u know how that goes) and everything else has the...
