My daughter has a Bradford White water heater # MITW40L6L910 for what
it's worth. The unit is only about 7 years old with relatively little
use. By that I mean there are not 14 people in the house taking 25
showers a day and doing tons of wash. It is ONE PERSON for years and
now TWO people.

I am told that the manual states that this unit has ELECTRONIC IGNITION
for the PILOT LIGHT.
I assume this means there IS A PILOT LIGHT but it lights like a
barbecue grill if it needs relighting.

NO hot water. Hubby tried to relight it and no good.
It has a POWER VENT on top.
I read somewhere that the POWERVENT is tied in to the igniton system.

QUESTION ?????????

Vent does not go on and the heater does NOT light up ? Correct ?

I did a lot of searching on the internet and found virtually nothing on
TROUBLESHOOTING these models. I have the NON-POWERVENT models and am 60
miles away. So I have not seen their unit to try and help.

I went to HOW STUFF WORKS and no good - info only on older
NON-POWERVENT models.

1) Comments/suggestions for TROUBLESHOOTING this problem ?? ( other
than the OBVIOUS one = call a PRO )

2)Any sites with info on these heaters with POWER VENTS ? I found none.

3) On POWERVENT models, if they need to be replaced, does the VENT
ASSEMBLY just hook on to the NEW HEATER ???

4) Do the POWERVENT assemblies have a UNIVERSAL plug ???

TIA

On my powervent water heater the power line goes directly to the thermostat.
Unless it is working properly (closing the circuit to the vent motor,
ignition, etc), nothing else starts.

When the thermostat calls for heat, the blower on the vent starts. The
airflow builds and trips a switch that fires the electronic ignition. When
the ignition coil heats, then the gas supply to the burner turns on. You
can hear things happen in sequence. There is a series of clicks followed by
the whoosh of the gas flame.

But, the circuitry is complicated because of interlocks. Without someone
who can check the circuitry, there is little you can do by remote control
except perhaps make sure that the heater is getting power. Certainly check
the circuit breaker and if the heater is plugged into an outlet, make sure
the plug is tight and that there is power at that plug.
