PROBLEM: Normal operation – No call for cooling with 2-wire connection or indoor unit not pow-Offered.
CODE: 1 pause
PROBLEM: Normal operation.
PROBLEM: Communication with wall control lost. Check wiring to wall control, indoor and outdoor units.
PROBLEM: High pressure switch trip. Check refrigerant charge, outdoor fan operation and coils for airflow restrictions.
PROBLEM: Low pressure switch trip. Check refrigerant charge and indoor air flow.
PROBLEM: Outdoor unit control board has failed. Control board needs to be replaced.
PROBLEM: The control voltage is less than 15.5v for at least 4 seconds. Compressor and fan operation not allowed until control voltage is a minimum of 17.5v. Verify control volt-age.
PROBLEM: Outdoor air sensor not reading or out of range. Ohm out sensor and check wiring.
PROBLEM: Coil sensor not reading or out of range. Ohm out sensor and check wiring.
PROBLEM: Improper relationship between coil sensor and outdoor air sensor. Ohm out sensors and check wiring.
PROBLEM: Compressor voltage sensed after start-up, then absent for 10 consecutive seconds while cooling demand exists. Possible causes are internal compressor overload trip orloss of high voltage to compressor without loss of control voltage. The control will continue fan operation and wait 15 minutes to attempt a restart. Fault will clear when restart is successful, or low voltage power is cycled.
PROBLEM: Compressor voltage sensed when no demand for compressor operation exists. Contactor may be stuck closed or there is a wiring error.
PROBLEM: Compressor voltage not sensed when compressor should be starting. Disconnect may be open or contactor may be stuck open or there is a wiring error.
What Our Clients Are Saying About Us
I would recommend KDM for sureOctober 10, 2020
Dan was very friendly and polite from the start. Did exactly the work that we talked about on the phone, and was very quick making a late evening call on a Sunday. Tested all the joints and even painted the gas lines. I would recommend him for sure.
I would recommend KDM for any of the services they provideOctober 10, 2020
I had a 2nd hand pool heater hooked up and needed help getting it fired up. So I contacted Dan at KDM to see if they could help and was pleased he could make it over within a couple of days. He checked out the gas piping for leaks and proceeded to analyze the components of the control system and determined a faulty pressure switch was likely preventing operation. I was able to source the part and Dan was able to make a 2nd call within a day to install and complete the job. So in summary, I would recommend KDM for any of the services they provide.

Daniel and Steve were amazing, very professional work and courteous….never dealt with more friendly and knowledgeable Hvac technicians.
I would not hesitate to hire Daniel and his crew againOctober 10, 2020
Asked for quotes on a A/C and furnace after 17 years when the A/C unit broke down. I contacted a few HVAC contractors including KDM. Daniel could not have been more helpful and responsive and after reviewing the quotes decided to hire him for the job. Could no have made a better choice. Daniel was patient and upfront and answered all my questions when asked. He upgraded my A/C unit for the same price after the original unit we agreed upon was back ordered. The crew came when they said they would an completed the installation in a timely and orderly fashion.
I would not hesitate to hire Daniel and his crew again. In fact he is coming back to deal with another issue I have next month!
Job well done.
I definitely recommend KDM Home & gas for othersOctober 10, 2020
I was looking for someone who can do the gas line connection on a weekend and I found the right guys with KDM Home & Gas. Daniel came on Sunday morning to do the work. He installed the new gas line, connected the new gas stove, confirmed no leaks and ensured everything works fine. It was a really hot day outside but he did an excellent job.
