My sister called me after having a very expensive service call. She has a Burnham LE with a Beckett. She read the invoice to me. On it was this long list of new parts. On it, was a new motor for the Beckett. They said the motor had a hot spot.

What is that?

That long list of parts, I got an idea what that is!

    hot motor spot

    While I have never labeled this problem as such, motors convert current into mechanical movement & give off heat. Too much can cause hot spots due to tight bearings, insulation of winding break down, poor electric connections. I would simply put motor replaced due to overheating caused by ....

    I also would have performed a combustion test and adjusted for peak operation eff. since this affects the combustion. I would have written amp, volt readings for the motor and smoke spot, draft overfire and flue draft, stack temp and CO2 radings for the combustion and listed the end efficiency burn rate which should be around 80% + or minus due to the desgn and conditions. 83%.
