Question about Dimplex DS5598 Mid-Size Heater

Heat turns off

When the heater is initially turned on everything works okay. Then after a few minutes, I hear a click, see a bright flash on the underside of the heater, and the heat no longer comes on (even though the blower, etc. is still working). The heat never comes back on unless I turn the heater off for several minutes.

Sounds like the high limit switch on the heater is kicking off. The flash is the switch shutting off the heating element. The only way to reset it is to turn unit off for about 5 minutes. Possible problems are: 1.) Bad thermostat 2.) blower motor not turning fast enough which means motor is bad.

This is normal, leave it on for an hour and see if the room warms up.

The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

Display says "CFH" but heatert wont fire up. Just makes a clicking sound

You don't have gas supplied to the heater. It sounds like you have a gas powered unit and the clicking you're hearing is the sparker sparking.

Ignition is locked out unit will not fire

Turn it off at the black toggle switch inside the front panel or turn it off at the breaker for 2-3 minutes
Then try again.
Check that flow is good, gas is on ect...
Is it saying lockout on the display?
If not then as you fire it up after cutting power keep the panel off and watch the ignition control red diagnostic light.
The blinking sequence of that light should point you in the right direction. There is typically a label that will tell you what the blinks mean.

Had a power outage yesterday now heater won't ignite. No error codes.

bo = 'Bypassed Operation'
heater is now controlled via your automation system.
Create a heat call, turn solar off if active.
Heaters should be set to auto on.

Eheat will not come on

When resetting anything electronic, leave switched off for about 15 mins. The electronic boards store the memory of any failure or problem and switching off for only a few seconds or minutes will not reset the board. Turn off at the mains supply not the wall control.

2 years old B&D bread machine. Motor doesn't turn. Didn't wait long enough to see if the heater is working.

Hi keneddy,
Always wait a few minutes to see if your bread machine start to mix after a few minutes. If the oven chamber is cold it will gently warm up a few minutes before it starts to knead/mix. This can sometimes take anywhere from 4-5 minutes and longer. If it doesn't start kneading after about 20 minutes then you do have a problem. Whole wheat programs often warm up before any kneading begins. All you will hear is a faint clicking noise while the heat comes on.

Freezer seems to be partitioned. The bottom part will freeze water but the top portion will not! Seems to work well after it has been unplugged for awhile and allowed to defrost. But , the vent for both...

It sounds like you have a failure of the automatic defrost system. This system has 3 components

- timer, this device provides power to the compressor for cooling then changes to the defrost mode every 8 - 10 hours and provides power for the heater

- heater, this is located just below the evaporator and clears the frost from the coils

- terminator, this device turns the defrost cycle off and prevents over heating during the defrost cycle.

To test the components locate the timer, it is usually on the back or in front behind the kick panel; it looks like this

The white piece can be turned either by hand or a flat blade screwdriver, turn it clockwise slowly until a positive 'click' is heard. Once you hear this stop and wait, you will be in the defrost cycle, if you open the door after about 5 minutes you should hear the water sizzling on the heater faintly behind the back panel inside the freezer. If you do hear that then the heater and terminator are okay and you need to replace the timer.

If you do not get heat you will need to unload the freezer, and remove the back panel. Behind there is the evaporator and below that is the heater. You will have to test the heater with an ohm meter it should read under 100 ohms.

The terminator is clipped to the top of the evaporator and should read 0 ohms when it is cold.

Buzzing sound when aux heat comes on

Sounds like it could be a effiency function to warn you that the heat elements are on. Check your thermostat manual and see if you can turn this feature off. If this is not a feature then the thermostat may be wired wrong or something in the circuit may be trying to short out.
