Heater stopped working in bedroom

[Phil Ayala]

The heater won't work in the bedroom of my Beaver Patriot 2004. However, its working fine in Zones 1 & 2. The thermostat appears to be working properly but the heating fan doesn't start when I activate the wall switch. Any trouble shooting ideas? I set the thermostat temperature high but no results.

Phil,
Check the electronic controller in the Aqua Hot bay. First thing I'd so is to push the reset button with a non-metal probe and see it that resolves the problem.  If not, verify that both circulation pumps are working, the zone indicators are illuminated and the low voltage cutoff is not red. Indicators for all these should be green. If any are red, you may have an electrical overload condition in that circuit. You may have 4 zones, Living Kitchen, Bathroom, Bedroom, and Tank bay.
There is a downloadable shop manual with a trouble shooting guide on the Aqua Hot web site also.

If the switch you are referring to is the High/Low speed rocker switch, you might check the back of the switch for broken wires or lose connections.  Mine is on the cabinet for the old bedroom TV and the wire connections had broken.  Now that the CRT TV is no longer in the cabinet, access is easier.

When ours was a year or so old, one heat exchanger quit.  Fortunately it was readily accessed under a removable drawer, and I found a loose wire to the unit's fan.  Easy fix.
