This answer is only if you do not have a gas furnace. I have had several customers with brand new homes and units with black soot everywhere. One even tried to sue us even though the system we installed was all electric. Well it turns out they each were burning candles in there home. Yes candles. Our builder hired an independent inspector. The candles all came from the same name brand department store.

Is this an older gas heat unit? If so, you may have a burnt out heat exchanger, this can be dangerous.

Can you see the condition of the coil itself? If it is blocked this could be a cause for the frozen coils. Also, check the condition of the blades on the indoor fan. Dirt and dust accumulation on the blades reduces airflow.

DO NOT buy a RUUD system. I purchased a complete system in 2010 & have had multiple issues since - - new coil, high humidity levels, condensation on my walls when the furnance is on, and now when the outside temp is 90+ degrees the AC unit shut off and only blows hot air. THey've replaced the "board" and I was told that RUUD is aware of multiple problems with the 2010 units but will NOT recall them.

Black soot is on the walls & ceiling around the baseboard heaters in the rental house that I live in. What is causing this & how do I clean this off?

If these are electric base board heaters, that is probably not soot, but instead mold. Put a little bleach in a spray bottle and try spraying it right on to the black soot looking stuff and see if it will disappear. If it does, it is mold. Bleach will kill the mold.

If these are gas heaters you need to call a service man NOW. Black soot is a sign of gas burning raw and can be very dangerous. Turn them off if this is the case.

Hello, this sounds like a flame sensor issue or high limit switch problem. First, turn off power to the Furnace and remove flame sensor, it is a small metal rod on the opposite side of the igniter, use some steel wool to clean it up and reinstall it. If that does not solve the problem then inspect you filter, blower wheel for dust or dirt, also make sure the blower motor is running at the proper speed. I hope this helps.

An ozone smell from the furnace set off our smoke alarms, No visible smoke. Model UBHC21J18....

The smoke detectors may be clogged with dust and lint. Remove the covers and spray with compressed canned air with a straw nozzle (like you clean your computer with) to clean them. Hold the compressed air can as upright as possible when using it. Smoke Detectors should be cleaned at least once a year.

Please let me know if this solves the problem.

2.5 RUUD AC not working, power must be getting to the unit.

Have them turn the outdoor unit off and wait a few minutes. When they turn it back on they should here
the fan and the compressor come on. They are to different sounds.

If they think that they have both come on, tell them to check the black insulated suction line. it should at least cold to the touch. If not it could be a freon issue.

If the line does get cold, have them checkthe filter in the house. If that is ok tell them to turn the power off
to the outside unit. Take a garden hose and wash
the outside coils on the outdoor unit,be carefull not to
smash the fins. Wash them at an angle from top to bottom.

Hello, I have a rbha-17 electric heat system. My

the orange or blue wire should go to the heat pump and energize the reversing valve and the compressor should be running when the heat pump is on. All it does is reverse the flow of refrigerant and pull btu's from the outside air and deliver them to your house. Check to see if your aux. heat is coming on with the heat pump. If it is electric furnace, this will help explain why your bill is so high.

Ruud 12 seer heat pump not heating

It sounds like the unit is tripping off from high pressure. Check you filter and indoor coil. You may have low air flow inside that is causing the refrigerant pressure to be to high.

Wiring a retrofit soft start blower into a Ruud 5T/100k gas pack

Chances are, you've smoked the motor. You basically put 120 volts across the speed windings of the motor when you did this.

What you need to do is, with the new motor, you will have neutral, and speed 1, speed 2, speed 3, etc. Hook one of the original black wires to neutral (it would be best to trace which of the two black wires is connected to neutral, and connect this one.).

Black on the new motor is probably High speed, red is probably low, orange is medium speed. Hook the remaining black wire to one of these, and no more than one of these, or you will smoke the motor again.

Attach a wire cap and/or electrical tape to the remaining wires to insulate them from contacting anything else.
