You do not program the wall control. Make sure the wires are still connected. The LED should be on. There is always the chance that it may have just quit on you.

April through October, spray monthly (or only when needed) with the modified Cornell University organic spray (see formula below) to control black spot, powdery mildew, spider mites, and aphids. Modified Cornell Formula: Mix into one gallon of water, in the order listed: 2 tbsp. of ultrafine horticultural oil (such as Sunspray oil) 1 heaping tbsp. of baking soda 1 tbsp. of fish oil/seaweed emulsion 3-5 drops of Superthrive® 1 tbsp. of mild dishwashing soap (such as Palmolive green -- but see note below) . [Note: Labels on newer containers of Sunspray oil indicate that it now contains an emulsifier. In that case, the dishwashing soap can be omitted.] Mix well and spray with a pump-up sprayer late in the evening, after first watering your roses thoroughly and spraying them with the hose to scare off some, most, or all of the beneficial insects. DON'T ADD VINEGAR. NEVER USE ANY TYPE OF FISH OIL/SEAWEED PRODUCT CONTAINING SULFUR WITH A HORTICULTURAL OIL SPRAY. AND NEVER MIX A CHLOROTHALONIL FUNGICIDE (e.g. Daconil or Fung-onil) WITH HORTICULTURAL OIL OR USE THEM ON ANY PLANT WITHIN 10 DAYS OF EACH OTHER. For black spot control, it is important that you spray all of the plant's wood, as well as the foliage. It has been found that the black spot spores reside in lesions in the canes and that they attack, not only the foliage, but also the canes and prickles. Used with permission from the Field Report

Thank you so much mike_home. The unit was installed sometime 2003. I realize it is coming to end of its life span. It is actually scaring me to replace anything and find out more issues as well. I will take your advice on the harness.The cost can add up quickly. I rather downgrade the system and get a new one. I called the electric company to find out about the power surge. There was none reported.The maintenance company was not able to tell me why it might have happened and they have never seen such thing before. The hot surface igniter was also turned on and stayed on during the incident which probably made the problem worse. I am not sure what other things were on or off. Long term damage is unpredictable.There was also so much water around the unit.So I am leaning towards replacing the furnace . Does anyone have an idea about the figure that I might be looking at considering it has to be something compatible of course? I am not going to get anything this fancy but it has to perform in similar manner. Thank you!
