Safety Information
Precautions to be observed before and during servicing to avoid
possible exposure to excessive microwave energy
Do not operate or allow the appliance to be operated with the door
open.
Perform the following safety checks on the microwave appliance
before activating the magnetron, or other microwave source. Perform
repairs as necessary: (1) safety operation, (2) proper door closing, (3)
seal and sealing surfaces (arcing, wear and other damage), (4)
damage to or loosening of hinges and latches, (5) evidence of
dropping or abuse.
Before turning on the microwave power for any service test or
inspection within the microwave generating components, check the
magnetron, wave guide or transmission line, and cavity for proper
alignment, integrity and connection.
Any defective or misadjusted components in the safety, monitor, door
seal and microwave generation and transmission systems must be
repaired, replaced, or adjusted by the service procedures described in
this manual before the appliance is released to the owner.
A microwave leakage check to verify compliance with Federal

Technical Information
H4080BM Speed Oven
Service Information
Service should only be performed by qualified personnel; in
accordance with all applicable codes and/or regulations.
Ensure the appliance is disconnected from the main power (i.e.
shutting off the appropriate circuit breaker) before performing service
procedures.
Danger – High Voltage!
Even with the appliance unplugged (i.e. circuit breaker shut off) high
voltage power remains present at the following components and poses a
risk of electrical shock:
High Voltage Transformer (T1)
High Voltage Capacitor (High Voltage Unit) (A4)
Diode (V1)
Protective Diode (V6)
Magnetron (G2)
Before performing any service procedure(s) the high voltage
capacitor must be fully discharged! Refer to the “High Voltage
Capacitor – Discharging Procedure” (5.3) for further information.
Danger!
Never attempt to measure voltage in the high voltage circuit.
Microwave Energy
Danger!
To avoid severe internal burns – never expose yourself to microwave
energy under any circumstances!
The Magnetron and/or microwave generator should only be serviced
by qualified service personnel trained on microwave service
procedures.
All intake and exhaust ports, vents, flanges, gaskets and seals are in
the appropriate condition and sealed where necessary.
Never operate the appliance without load (i.e. food or water present in
the cavity)
Never look into an open wave duct or the antenna while the appliance
is in operation.

4.0 Description of Function
4.1 Door Safety Switches
1 1F6/6 Primary Door Safety Switch (left)
2 2F6/6 Door Safety Switch (left)
3 3F6/6 Primary Door Safety Switch (right)
4 4F6/6 Door Safety Switch (right)
5 5F6/6 Door Monitor Switch (signal to electronic)
Figure 4-1: Door Safety Switches and Monitor Switch Locations
The door safety switches are located behind the control panel near the
top left and right edges of the front door, as shown in Figure 4-1. Each
side is equipped with a primary switch (1F6/6 left and 3F6/6 right); and a
secondary switch (2F6/6 left and 4F6/6 right). Two contact pins at the
upper edge of the door activate the switches. The safety switch circuit
allows power to certain components (i.e. high voltage circuit) only if the
door is closed.
In the event a primary door safety switch fails (in the shut position) current
is directed to the electronic (3N1) and the 10amp fuse (F8) interrupts
power; preventing any further usage of the appliance.
In addition, a door monitor switch (5F6/6) is installed on the left side and
provides the electronic with the status of the position of the front door.
This switch can be checked in the service mode.
18

Technical Information
H4080BM Speed Oven
Note:
Should a safety switch require replacement, the complete assembly must
be replaced as a single component. The switches are not available as
separate components.
Important!
To ensure proper operation of the safety switches, the door must be
checked and adjusted (Refer to Section 5.9).
4.2 Cooling and Vapor Ducting
Figure 4-2: Cooling and Vapor Ducting
4.2.1 Cooling Fan (M2/1) Specifications
Voltage 120VAC, 60 Hz
RPM 2700 min
Fan (coast-down) 1200 min
Switching Temperature 149°F (65°C)
Table 4-1: Cooling Fan Specifications
19

Technical Information
H4080BM Speed Oven
4.2.2 Cooling Air Intake
Refer to Figure 4-2 – Cooling and Vapor Ducting. The cooling fan (Item 1)
draws in air through the vented openings in the appliance. The incoming
air is used to cool the appliance, the electrical components and the
surrounding cabinet on all sides.
4.2.3 Cooling Air and Vapors Path
Refer to Figure 4-2 – Cooling and Vapor Ducting. The cooling fan moves
air into the back area of the appliance (Item 2) passing over the
magnetron; and then is directed back toward the front of the appliance
and exits from the front of the appliance.
4.2.4 Air-Path During Microwave Operation
Refer to Figure 4-2 – Cooling and Vapor Ducting. The release element
(Item 4) opens, permitting a small amount of air-flow to mix with vapors in
the oven cavity. The air/vapor mix is directed through the cavity port
(Item 6) to the vent (Item 7). The air/vapor mix, again mixes with cooling
air.
Service Tip:
Should the air vent not open, air cannot exit and moisture will accumulate
in the oven cavity.
4.2.5 Air-Path During Convection, Broiler and Combination
Refer to Figure 4-2 – Cooling and Vapor Ducting. The air vent (Item 5)
remains closed. Vapors move via the cavity port (Item 6) to the vent (Item
7) and mix with cooling air.
4.2.6 Cooling Air and Vapor Exit
Cooling air and vapors are directed out of the appliance through the vent
above the air guide in the front of the appliance.
4.2.7 Cooling Fan (Coast-Down)
The cooling fan operates during the cooling phase and protects the
appliance from high temperatures and moisture. It shuts off when the
temperature in the oven cavity reaches about 158°F (70°C).
