Sf-42Q 233043: Amp draw?
With the blower shroud on the draw fluctuates: low 6.34 to a high of 8.27 during a ten to twenty second test, after the furnace was on for a few minutes (eliminating start up draw readings). Does this drastic fluctuation mean the blower is going? There is no noise or lack of heat on the LP side. However the issue is on the electric side. RV Comfort Systems (CheapHeat) is saying it's likely I am not getting the full 5k watts from the electric coils because the blower is not supplying the required air flow to do so. When air flow is reduced the CheapHeat unit is designed to reduce heat output by shutting down coils units (1800, 3750). As a secondary measure to prevent overheating there is a 200 degree fusible link. I'm my case there is enough air flow for the coil assembly to put 3750 watts through the heating coils. I've looked all over the net for normal amp draw on 233043. The only information I can find is 11 amps. However this is stated as the entire furnace (Suburban SF-42Q manual).
So are my reading low for this model? If not, is the fluctuation normal? I can understand some fluctuation during start up and open/closing doors, windows, vents, or registers.
