Sub-Zero 736TCI 3 leaking water under crisper drawer

krazytech — Sat, 12 Dec 2009 06:14:23 +0000

Sub-Zero 736TCI 3 leaking water under crisper drawer. With water dripping out the door it was time to call for service.

Sub-Zero fresh food compartment uses a cycle defrost to keep the evaporator free of frost. A cycle defrost just turns off the compressor and lets the warmth of the refrigerator defrost the evaporator. When the thermostat reaches the lower limit it turns off the compressor with the compressor turned off the evaporator will defrost as the frost melts off the evaporator. Water drops down off the evaporator into a trough. the trough is angled to the center where there is a drain hose. This drain hose runs under the bottom of the fresh food and out the back then under the freezer on to a drain pan where the water sits to slowly evaporate into the air.

The problem starts with water in the drain hose becomes frozen . With just a cycle defrost the drain hose never thaws plugging the drain hose and the drain trough is over filled with water this water spills over the drain trough and into the floor of the fresh food compartment. Sub-Zero has a fix for this problem a drain heater kit PN#753857. This drain kit includes a cable heater and a wire harness. the wire harness connects into the fan motor. As the fan is powered so is the drain heater keeping the drain clear of ice.

Frigidaire dishwasher with Blinking uo error

krazytech — Thu, 03 Dec 2009 04:01:28 +0000

Frigidaire dishwasher FDB4315LFC0 with a flashing uo error. As soon as the customer started the dishwasher a uo error would come up on the display. So the customer would have to do dishes by hand. With dishpan hands it was time to call for service.


: flashes Er then uo error

uo is a vent not closing error. The vent could be blocked from closing or most likely the vent solenoid has failed . You can hear a audible click noise when the vent cover opens and closes. This vent assembly is located on the top right side way in the back. there is a lock ring inside the dishwasher 1/4 turn to the left and it will release the vent. the newer vents have a separate wire harness that will come with the new vent . The older vent assembly has the harness built into the vent. So you will need the new wire harness with the new vent assembly.

The uo error can also accrue with a control failure not recognizing that the vent is open. the failure of the control is less likely to happen .

Wolf oven will NOT heat

krazytech — Mon, 30 Nov 2009 08:13:24 +0000

Wolf R364G Gas Range would not light. With a turn of the knob the indicator bake light comes on but nothing else happens NO heat .. The customer needed her oven to bake a large Thanksgiving turkey . Time to call for service.

With a non-contact voltage detector I check for voltage to the igniter. The blinking light indicates that I have voltage to the igniter. With no glow at all, It was time to replace the Bake Igniter PN# 813541. Turned the knob to off and switched the breaker to the off position to cut the power to the range. I removed two screws that hold on the burner plate. Also removed two screws that hold the gas orifice. Then removed two more screws hold the burner in place removed them. slid the burner over to the left to get access to the two screws that hold the igniter to the burner. Removed the two screws and the igniter. Installed the new Bake igniter PN# 813541 then replaced the burner, gas orifice and burner plate screwed them all back together. With a 16 gauge insulated crimp-on butt connector I stripped and crimped one of the igniter wire. The other wire was replace off of the gas valve .

Frigidaire side by side making Too much ICE

krazytech — Mon, 30 Nov 2009 06:09:19 +0000

This Brand New Frigidaire refrigerator model number FPHS2699KF as making more ice then this couple can use to cool there drinks. Ice was overflowing the Ice Bucket and falling down to the bottom of the freezer. So it was time to call for service.

This is a common problem with Frigidaire’s side by side refrigerator Ice maker when the ice dispenser is not used very much the bail arm of a ice maker raises then drops. when the ice blocks the arm from returning to the resting position. It keeps the water valve from opening stopping Ice production.

The problem with this Ice maker is that when the bail arm drops it pushes the ice out of the way. Letting the bail arm return to the resting position and NOT stopping the production of ice. When the bail arm pushes the Ice out of the way it over fills the bucket and ice drops all over the freezer.

The fix is a bail arm extension PN# 218513800 This part is an add on that slides over the bail arm and clips to one side of the bail arm. This will keep the bail arm from pushing the ice. It will also lower the level of ice in the ice bucket keep all the ice in the bucket.

Dacor Cooktop burner will not light

krazytech — Sun, 22 Nov 2009 05:36:32 +0000

Dacor cooktop PGM365SLP left front dual D Burner will not light.This is the most used burner

so time to call for service.

Dacor cooktop left front burner igniter would click but no gas was making it to the burner and no flame to heat the water for spaghetti.

Removed all the grilles, burner caps and burners. Then unscrewed 15 torx screws on each burner bases and remove all 5 knobs by pull them up. Removed each burner base and unplugged all 5 igniter wires.

Now the drip pan can be lifted off.

Each gas valve is connected to a flexible aluminum gas hose. Each gas hose has a brass orifice or jet that control how much gas it feed to each burner. After the orifice is a venturi which Gas is introduced into the air stream through small orifice at the narrowest part of the venturi. Fuel flows in response to a particular pressure drop in the venturi is adjusted by means of precisely-calibrated orifices or jets, in the fuel path with the gas. then there is the main tube that is slid into the gas burner. This main tube had fell out of the burner base. Gas was fill under the cooktop not going to the burner. I replaced the tube, slid it into the burner base bend the inlet tube a little to keep the tube in place. Put it all back together making sure each igniter wire when back to the correct burner..

Turned the knob and poof the burner was working again.

(Parts used) None

KitchenAid Dishwasher with Three Blinking Lights

krazytech — Thu, 19 Nov 2009 05:14:13 +0000

KitchenAid model # KUDPO1ILBS2 would only blink lights and NOT wash the dishes.

So It was time to call for service.

Blinking lights (Normal)-(Sani/Rinse)- (Cancel) but would not go anything else. Removed all six of the 15 torx that hold the control panel on and the two more screws that hold the door latch. unplugged and plug in the control panel three time and the dishwasher when into test mode. It was time for a New control panel as the keypad had failed.

If the dishwasher would not go into test mode. Then you will need a control.

Removed the control by pressing two clips on the left of the control. Popping the control up then pulling it to the left emoved it from the panel. Unplugged the key pad ribbon connector from the control. Then unscrewed the door latch slid it into the New control panel. Snapped the control into the new panel and plugged in the ribbon connector. slid the panel back into the door and replaced all 6 screws and 2 screws for the door latch.

Turned on the power and it was washing dishes again.

Dacor ER48DSH/NG indicator light Not working

krazytech — Sun, 15 Nov 2009 02:36:08 +0000

This new Dacor ER30DSH/NG Gas range has the signature Dacor blue indicator lights which illuminates each knob when the surface burner is turned on. The indicator light is very important on a gas range to show the user that a burner is on especially when the burn is on a Low simmer when a flame is nearly invisible. Time to call for service.

New LED with larger black varistor

The indicator lights are low voltage LED controlled by cherry micro switches on each gas valve. As the knob is turned a cam on the gas valve triggers the switchs allowing voltage to the LED. With these LEDs a small voltage change results in a large change in current. It is therefore important that the power source gives the right voltage. If the voltage is too high the current will go above the maximum rating, heating and potentially destroying the LED. As the LED heats, its voltage drop decreases further increasing current. LEDs should only be connected directly to constant-voltage sources. A varistor are a simple way to stabilize the LED current. A varistor is a non-ohmic variable resistors. known as a metal oxide varistor, or MOV. This contains a zinc oxide grains, in a matrix of other metal oxides, between two metal plates. The boundary between each grain forms a diode junction, which allows current to flow in only one direction. The mass of oriented grains is electrically equivalent to a network of back-to-back diode pairs, each pair in parallel with many other pairs. When a small or moderate voltage is applied across the electrodes nonlinear current-voltage in which the MOV has a high resistance at low voltages and a low resistance at high voltages stabilizing the voltage and absorbing small voltage surge. Working like a mini capacitor . Varistors do not absorb a significant percentage of a lightning strike, but they can stabilize low voltage.

Cherry micro switches and cams on gas valves

Dacor has revise the varistors on there LED three times each time adding a larger capacity varistors to protect the LED. Dacor tech line also recommended that we replace all LED when one is burn out. Remove the four drip pan trim.then the two center porcelain covers slid forward lift up at the rear then side back to remove. remove the burner and two crown burner there is a tool under the right side toe panel. Lift up the three drip pans and four screws remove the front brace. This gives you access to all 6 pn# 100121 LED lights they just unplug. reverse the steps and tested each indicator lights.
