Question about Ruud UBHC Air Conditioner
The Watt Restrictor in my Rheem 11kW Electric Furnace (RBHC-14J11SFA) is shutting off 2 out 3 heating elements, meaning the room I am trying to heat never reaches its setpoint.
Consequently, the furnace fan and a single heating element runs continuously, never reaching the setpoint.
Each morning, the room is around 56F, the setpoint is 65F. It takes 90min to reach 61F, and it does not get any warmer. Assume the outside temp is around 15-20F.
I used a current clamp to verify only one heating element is energized MOST of the time; however, the other two elements do turn on for short periods before turning of again.
Is there any way to safely disable/override the Watt Restrictor? I want to prove that the three heating elements can achieve the desired temperature rise.
Note: I have a Lux single-stage thermostat. Wiring of the thermostat matches the recommendation on the furnace's wiring diagram.
Unfamiliar with watt restrictors.
heat strips have 2 safety devices, a thermal overload, they get to hot they shut off, cause not enough air flow increase fan speed this device is auto reset. a fusible link a fail safe to thermal over load, no reset and sometimes replaceable. if this does not help would like to ask you a few questions. one of the buildings i take care of has 200 + reem/ ruuds all electric heat. if a part is defective replace, please do not by pass. safety frist.
