Frequently Asked Questions
General & Technical Support
Q: How long is my warranty period?
A: Please get in touch with a local ClimateMaster Distributor or Representative for warranty information.
Q: What do I need to do to get technical help from the factory?
A: You should contact your local distributor for any technical assistance. They should be able to assist. The distributor can contact the factory for assistance if needed.
Q: What is a Service Desk Ticket, and how can I start one?
A: A Help Desk ticket is a tracking system that allows communication to be tracked and available to all ClimateMaster Technicians. To start using the help desk system, go to the Business Center under "Help," select "Technical Support Center," and register. Alternatively, visit Techsupport.climatemaster.com to register.
Equipment & Components
Q: What are the pressure settings of HP/LP switches?
A: Pressure ratings of the switches installed in a unit may vary from unit to unit. Please contact ClimateMaster technical service for the pressure ratings of your specific equipment. Please be prepared to provide unit information when calling ClimateMaster technical support.
Q: Why won't my compressor come on?
A: Check for 24V at Y to ground. If you have 24V, check for 24V to ground on the first red wire on HP pin 1. If you also have 24V there, it is a bad control board.
Q: Why do we have a drier on the discharge line?
A: In most ClimateMaster heat pumps, a muffler is installed in the discharge line. This is not to be considered a filter drier.
Fault Codes & Diagnostics
Q: What does "Test Mode" do to the operation of the unit?
A: Test Mode allows service personnel to check the operation of the Control promptly. By momentarily shorting the test terminals or switches, the Control enters a 20-minute Test Mode period during which all time delays are sped up by 15.
Q: How do I retrieve a fault code?
A: In Test Mode, the Alarm Relay will cycle on and off, similar to the fault LED, to indicate a code representing the last fault at the thermostat. Count the number of flashes and compare it to the “LED and Alarm Relay Output Table” in the unit IOM.
Q: What does the number of flashes mean?
A: “Flashing Appropriate Code” means that the Fault LED will continuously flash a code representing the last fault in memory. If there is no fault in memory, the Fault LED will flash code 1.
Q: What does a single (1) flash mean in test mode?
A: Code 1 indicates there is no fault in memory; stated differently, the Control has not faulted since the last power-down to power-up sequence.
Q: What is the difference between a slow flash and a fast flash?
A: A slow flash is 1 flash every 2 seconds. It is displayed when the Control is in Fault Retry mode. A fast flash is 2 flashes every 1 second. It is displayed when the Control is in Lockout mode. The compressor will not be energized in Lockout mode. See the IOM for more details on both.
Q: What is a CO fault?
A: “Condensate Overflow” Code = 6. The Condensate Overflow sensor must sense overflow levels for 30 continuous seconds to be recognized as a CO fault. Condensate Overflow will be monitored continuously, including during the compressor run cycle. The Fault LED will immediately begin flashing Code 6 when a Condensate Overflow Fault occurs.
