Ruud Problems I have a Ruud Acheiver 90, I'm having some problems, the rollout (burner) limit switches are opening, and there is an electrical burning smell. It seems that sometimes the squirrel cage isn't kicking on, but when I reset manual limits and give the squirrel cage a manual turn, the heater runs fine, sometimes. I guess what I'm asking is: would the fan motor only work sometimes, would the ignition plug give off an electrical burning smell (it's lighting fine), there is a separate ther

There is a switch on my 1 1/2 ton Ruud furnace/Air handler that is not working properly. The unit would not turn on, even though the thermostat was working. I took the panel off of the air handler and found that a switch had been duct taped into the on position on the unit. Apparently, the tape had shifted and the switch was no longer in proper position. when i moved the switch, two green indicator lights lit up. When i turned the unit back on, the A/C worked. Clearly, there is a problem w

Furnace trouble Working on a Carrier sx from 1990, has three wire bi-metal pilot with spark and 100% lockout on the spark module. Homeowner says it only fails in cold o.d. temps (less than 35 degrees). Home owner finds unit off and silent, resets 120v and unit re-lights and runs. Don't know what parts have been replaced so far but it looks like a new spark mod. and the pilot was clean but I cleaned it again. Limit switch looks old but I think limit failure would cause the blower to run. Any idea

Furnace not firing: I have a Haier model HGA 080 N3H furnace that is blowing air but not igniting the burners.

The filter is clean, the gas line is open, the led light that indicates problems is functioning normally, the ignitor is switched to on, all cables attached between the ignitor and the burner are solid, and the thermostat is telling the h

I have a furnace that stopped blowing warm air. The indicator light states that the limit switch is open. Is there an easy fix that I can manipulate myself, or is this something I have to call in a repairman for?

The light fixture needed to be repaired. It never worked when I bought the house. New light bulbs didn't worked. I replaced the two ceramic light switches that had corroded wiring and reconnected blue to black and white to white. I have a dual wall switch that controls the fan and light. Now the light only works when the fan is on. The light on my other identical fan works without the fan on. Is the wiring problem in the fan or switch. The switches are different.

I have two (2) singel switches next to each other that turn on the lights in the garage and the other the lights outside. I bought two (2) 1595-SWTTRWCC4's and I would like to know how to install them. Each one has two black wires coming out of the Pass & Seymour. Out of the wall I see one red and one black wire going to one existing switch, and two additional black wires going to the other switch. Ground is no problem. How do I wire the both ? Thanks Guido
